5 Drill Bits Every Woodworker Needs and 1 You Don't - best drill bit for clean holes in wood
Austenitic stainless steels are primarily used for products that require strong corrosion resistance. Domestic, industrial and architectural products often use austenitic stainless steel. These could include:
Up cut vs down cutmilling
The benefits of martensitic steel mean that it offers a low cost, air-hardening metal with moderate corrosion resistance, which is easy to form, with a minimum chromium content of 10.5%.
Aluminium extrusion is ideal for both single prototypes and large-scale production, offering bespoke, high-standard, consistent cross-sectional profiles.
Often tensile strength is a critical factor in determining the best material for your project. We recommend developing an understanding of the forces and loads that will be experienced by your parts and comparing this against the various tensile strengths on offer. This will help you eliminate any materials that wonât offer the required strength.
A down-cut spiral router bit is the opposite of the up-cut. Down-cut spiral router bits are used for downward cutting in woodworking or materials that are prone to tear out or splinter like plywood, or veneers. A down-cut spiral bit will minimize the chips on the uppermost surface of the work. It’s beneficial for producing a clean cut on top of your wood while producing some tear out at the bottom of your cut. This router bit is therefore a great choice if you want to have neat and clean pockets in your project or if the good side of your project is facing upwards. When using a down spiral bit, the chips would be pushed into the cut and buildup, which would considerably produce more heat, cause burning, and reduce the lifespan of the router bit. When it is machined in a router table, it’s crucial to feed slowly to ensure safety as you would be struggling against gravity.
When arranging a quote with CNC machining companies such as Get It Made, check to see which stainless steel grades they offer; there may be common grades they stock or can easily source. Avoid specifying overly niche grades or branded materials as this can increase costs and lead times. You can find Get It Madeâs most common material grades on our individual process pages.
Upcutvsdowncutvscompression
An up-cut spiral router bit is recommended for most case usage. It’s great for plunging as it’s evacuating the chips upwards so you can do a straight plunge. For a woodworker who wants to make a dado or groove in straight-grain hardwood like walnut and maple, an up-cut spiral router bit would work better since it would allow for much greater chip evacuation and a cooler cut, which allows for faster cutting. When it is machined in a router table, an up-cut spiral router bit will pull the chips out of the cut. Since up-cut spiral router bits are designed to pull projects away from the work table, you should have enough hold-down clamps when working with smaller pieces.

A compression spiral router bit is a combination of an up-cut and down-cut spiral router bit. It splits the bit in half down the center, with an upward spiral first and a downward spiral following. The up-cut edge is on the tip of the spiral bit and a down-cut edge is close to the shank. This allows the bit to push the chips toward the center of the bit rather than outwards, and chips are thrown down by the top part of the bit while the bottom part is scooping them up. Accordingly, this gives you the best of both worlds, and your cutting material will retain a very nice and neat edge on the bottom and top edges, as well as producing a perfect trimming finish.
Up-cut spiral router bits are an efficient tool for moving chips up and away from the slot being cut with their upward spiral cuts. Because of this upward cutting direction, it sufficiently minimizes chips on the lowermost surface and leaves a smooth and nice finish on the bottom surface of the material but a rough top edge. It’s therefore the ideal option if you want to ensure that the good side of your project is facing downwards.
Duplex stainless steels, sometimes known as austenitic-ferritic stainless steel, have a two-phase metallurgical structure. Namely, duplex stainless steel contains both austenitic and ferritic phases. The strength of duplex stainless steel is higher than typical austenitic stainless steel and has additional corrosion resistance.
If you have specific hardness requirements for your parts, you may wish to consider heat treatment. Bear in mind that whilst heat treatment improves the hardness of your parts, this may come at the expense of other mechanical properties. Also, note that austenitic stainless steels cannot be heat-treated, thus eliminating this category from your material choice.
If cost is the most important factor for your project. Bear in mind, however, that the material cost is just one part of the overall cost. Try to reduce cost by reducing the number of machining operations and simplifying your parts as much as possible.
Cutting Material: Up-cut spiral router bits are by far the more versatile router bits than down-cut spiral bits. They are commonly used for making dados, mortise, tenons, and shallow grooves in bottom-veneered boards without tearing them out. Down-cut spiral router bits have a smooth cutting action, remove debris efficiently, and create clean edges on materials such as inlay, plywood, or laminated material. They are also suitable for carving and engraving designs and use in CNC applications. Compression spiral router bits made from robust solid carbide are typically super sharp and durable. It is perfect for cutting materials like double-sided veneers, softwood, hardwood, MDF, laminates, and composite materials as compression spiral router bits cut more effectively throughout and leave a cleaner cut surface on both the top and bottom of the material.

Austenitic stainless steels are known for their machinability and weldability, which mean they are often used in CNC machining. Due to its mainly crystalline structure, austenitic stainless steel cannot be hardened by heat, making them non-magnetic.

When considering the options of up-cut, down-cut, and compression spiral router bits, choosing the right router bit for your woodworking project is pivotal to achieving precision and quality in your cuts. Thus, it depends on how you want the final result to look. It is recommended to use an up-cut bit when cutting mortises because it effectively removes chips from the hole. Although a sharp up-cut spiral router bit works just as well, a down-cut spiral router bit is more frequently employed for shallow inlay work. Compression spiral bits stand out as a superior choice for many applications as they integrate the combined advantages of up-cut and down-cut spiral bits. By carefully considering the requirements of your specific woodworking task, you can determine which type of bit to use in each situation.

There are usually multiple factors that need to be considered when choosing a material for any project. With many different stainless steel grades available, it can be challenging to narrow down your choice. However, if you consider the following factors, you should be in a position to determine which grade is best for you.
When to use upcut spiralrouterbit
Stainless steel is an incredibly versatile metal and is often used for CNC (Computer Numerical Control) Machining and CNC turning in the aerospace, automotive and marine industries. Stainless steel is known for its corrosion resistance, and with various alloys and grades of stainless steel available, there are a wide variety of applications and use cases. This article will explain the different types of stainless steel's mechanical properties and help you determine the best grade for your project.
Precipitation Hardened Steel is the strongest steel grade, is heat treatable and has excellent corrosion resistance. Due to this, it is largely used for aerospace components, where extreme durability and reliability is needed from the part.
Cutting Action: The primary distinction between an up-cut and a down-cut spiral router bit is their edges are cut in the opposite direction of rotation. If the flute rises to the right when reading the flutes from left to right, you have an up-cut, it sends all the chips upwards, so it leaves you a clean bottom side. On the contrary, A down-cut is present if the flutes descend to the right. A compression spiral router bit has an up-cut which is approximately the first one-quarter of the cutting length of the router bit, while the remaining of it is a down-cut.

Martensite is a tough form of steel, and its properties mean it is a steel that can be heat-treated and hardened. However, it usually has reduced chemical resistance compared to austenitic steels.
Ferritic stainless steel contains around 12% chromium. It differs from other stainless steel forms due to its chemical composition and molecular grain structure. Unlike austenitic steel, ferritic steel is magnetic due to its body-centred cubic grain structure. It is commonly used for automotive parts and kitchen appliances with a lower corrosion resistance and heat resistance than austenitic steel.
With many years of experience, sheet metal parts can be a great low-cost option for certain high and low-volume applications.
Ferritic steel offers a high degree of resistance to stress corrosion cracking. This makes it a popular choice of steel for environments where chloride may be present. Stress corrosion cracking can degrade steel if exposed to a corrosive environment, particularly when exposed to chlorides.
Up-cut, down-cut, and compression spiral router bits are the common spiral router bits, they differ greatly from one another in some aspects.
In CNC router industrial applications, up-cut, down-cut, and compression spiral router bits are the usual cutting tools, and they come in different flute directions. A spiral router bit is generally used for plunge routing. Spiral router bits have angled cutting edges, so they slice through wood rather than chop it. As a result, they are superior at minimizing heat buildup, improving chip evacuation, and leaving a cleaner cut behind. In the field of woodworking, the selection of the optimal up-cut, down-cut, and compression spiral router bits stands as one of the many perplexing matters for many individuals. That’s why this blog will pick these spiral router bits to guarantee that you always obtain the most suitable finish.
PH steel is also used in the oil, gas and nuclear industries. This is because it offers a combination of high strength but generally a lower but workable degree of toughness. The most popular grades of precipitation-hardened steels are 17-4 PH and 15-5 PH.

Chip Removal: The way the flute goes determines in which direction the chips are pulled. Up-cut spiral router bits evacuate chips more efficiently and allow faster feed rates than down-cut spiral router bits. Down-cut spiral router bits will drive wood chips into the cut and buildup, and require slower feed rates. Compression spiral router bits provide better chip evacuation, smoother and faster cutting, and cleaner finish.
