Twist drill bits, also called fluted bits, are used on light metal, wood, plastic, metal, ceramic and masonry. This type of drill bit is works well for holes up to one inch in diameter and are useful for home repairs, maintenance and building projects with metal, wood or ceramics. This is the most common types of drill bits for home use.

Proper drill bit maintenance is not much different from maintenance for most tools, and it helps prolong the life of your drill bits and keeps them ready for the next job. Caring for your drill bits can also be a matter of safety; dull or damaged drill bits can create problems both in the work and for the worker.

Due to the carbon present in all steel (even mild steel), steel can be made with a hard surface while retaining a tough, flexible core. The mechanical change is more significant in medium and high carbon steel. Case hardening is accomplished by taking steel and heating its surface – either through extended exposure to flame or by heating it through electrical induction. This process causes a reaction with the carbon on the surface of the steel, resulting in a hardened skin.

Through-hardened steel is created by heating carbon steel all the way through and rapidly quenching it, usually in water or oil. This causes the carbon to react throughout the metal as the crystal structure of the steel changes form. When the metal is quenched, the crystal structure is locked in. Steel intended for use in sprocket manufacturing often undergoes additional heat treatment called annealing. Annealing can help to offset the brittleness that results from hardening, and allows steel workers to tailor the mechanical properties of the steel to suit its intended purpose.

Most drill bit sets are sold in a case with space to hold each bit in place. This keeps the drill bits from being nicked or scratched and also provides excellent organization. Each spot is marked for the bit's size and type, making it easy to quickly find the right bit for the project you are completing. If your set didn't come with a case or you've been buying individual drill bits, add a storage box with dividers to your tool set. Don't store more than two bits together and use a permanent marker to mark each space with the size and type of drill bit stored there.

Sized for their diameter, types of drill bits are constructed in a range of styles to help with specific tasks. You can find a drill bit set that includes many of the standard bits needed for home repair.

Drill bits come in a range of drive styles, and different options can be useful depending on the work you're doing. Here are a few common types to know:

The resulting product offers exceptional hardness all the way through the steel, providing a tough, resilient surface that is abrasion resistant. This makes through-hardened steel an ideal material for use in high-contact applications where increased tensile strength is an asset, such as in springs, hand tools, and high-end knives.

Auger drill bits can be used on wood and are ideal for large woodworking and building projects. Their screw-tip helps draw the drill and requires less pressure to perform.

The chuck is the part of the drill that attaches the drill bit. Most power drills for home use have a 3/8-inch or 1/2-inch chuck. Larger chucks come in 5/8-inch and 3/4-inch sizes, but are usually fitted on heavy-duty and industrial power drills and drill presses.

One question we get all the time is “What’s the difference between surface hardened and through hardened steel?”. While both products are optimal when used in the right application, they’re rarely interchangeable, and it’s important to understand their key differences to get the most out of your components. In this article we’ll examine the difference between the two products, and outline the strengths and weaknesses they have in an industrial setting, such as sprocket manufacturing

What is hardened steelvs carbonsteel

For industrial applications that require abrasion and corrosion resistance however, through-hardening can be an ideal choice, provided the work involves a relatively constant, low-impact load.

Through-hardening may be appropriate for work involving abrasive or corrosive environments with consistent workloads, where the risk of fracturing is outweighed by the benefits provided by the additional depth of hardness. This application is often seen in cement or aggregate plants, where a through hardened sprocket can often outlast a surface hardened sprocket by over 2-3 times! Some through hardened steel has superior strength/toughness properties than ductile case-hardened steel, but tends to be avoided due to cost. Creating a through hardened sprocket that has undergone sufficient annealing to act in place of a surface hardened sprocket is expensive, so the value-add this type of steel offers relative to case-hardened steel will be operation dependent.

It’s important to know that not all steel is the same, even before it is hardened. Varying levels of carbon content in the steel affect its ability to be hardened when exposed to high levels of heat. Alloying can also shape the composition of steel to achieve different mechanical properties (such as stainless-steel’s resistance to rusting).

To illustrate the importance of selecting the right steel composition and hardening option, consider that a high carbon steel that has undergone a heat-treating process in this manner can be as much as three or four times harder than an unhardened mild steel. Hardening is ideal for creating steel components that will experience repeated exposure to workloads, providing a long-lasting friction-resistant surface.

Forstner drill bits can be used on wood and are useful for woodworking. This type of bit creates a clean hole with a flat base. It also works better in a drill press than a handheld drill.

While through-hardened steel offers an incredible degree of toughness and increased resistance to corrosive agents, the process makes the steel more brittle. This greatly reduces its ability to withstand impact, such as a sudden load. If subjected to abrupt application of force, hardened steel is prone to fracturing.

A drill is one of the best additions to the home toolbox and is essential in just about any project, whether it's a quick decor change, major room upgrade or building addition. However, a good drill is useless without correct types of drill bits for the job.

When it comes to drills, there are two easily identifiable parts you need to know about – the shank and the chuck. The following information explains how drills and drill bits work:

The shank is the end of the drill bit that fits into the drill and is secured by the chuck. A round shank centers a bit in the chuck more accurately. The flat surfaces on a hex shank allow the chuck to grip the drill bit securely.

At DROP Sprockets, our sprockets are made-to-order with an intended purpose in mind, each requiring different base materials and hardening methods. While most sprockets are surface hardened to retain the ductile core of the material, the hardening method and depth of hardness are selected based on the required application.

Drill bits make holes in a variety of different common materials. These include different types of wood, metal, plastic, ceramic tile, porcelain and concrete. Different types of drill bits made for steel, aluminum, copper, cast iron, sheet metal, fiberglass, brick, vinyl flooring and more are also available.

Idler sprockets are often fitted with a round hub, often with a low-friction bushing or bearing insert to allow the sprocket to rotate easily as the chain goes by. These sprockets act like a spacer to support conveyor chain, allowing the contents to move freely along the length of the conveyor. Because idler sprockets rotate freely under a relatively light load, they can usually function without additional hardening. The ductile nature of the steel here is an asset, allowing these idler sprockets to absorb any sudden shock loads.

Drill bits are cutting tools. If you do a lot of home projects or heavy-duty construction work, periodically sharpening your drill bits will be necessary. Dull drill bits can increase time and effort needed to complete work and possibly damage the materials you're working on, and may even cause injury. A sharpening tool can be a good investment to keep your drill bits in top shape. More experienced DIYers can accomplish the task with a good set of grinding tools.

This guide highlights drill bit types so you can choose the right single bit or drill bit set to get your project off the ground.

Somewhere else in the machine, a drive sprocket is used to transmit power from the engine to the conveyor by use of roller chain. The sprocket attached to the drive shaft is placed under considerable stress, since it’s responsible for pulling the chain. The chain contacts the surface of the sprocket tooth while under tension from the motor, which is quite a considerable amount of force. These drive sprocket teeth are often hardened in order to reduce the wear from the chain over millions of revolutions. Generally surface hardening is preferred to keep the core of the sprocket ductile enough to handle shock loads without fracturing, while still providing durable teeth.

Surface-hardened steel is able to handle the impact of shock loads while still providing a tough exterior that resists wear, ideal for applications involving heavy cyclical loading. This combination of flexibility and hardness makes surface-hardened steel ideal for use in industrial machine parts, roller bearings, theft-resistant chains, and automobile camshafts, to name a few examples.

For most home projects, twist or brad point styles are usually the most useful drill bit types. You can always add other sizes and specialty drill bits as you need them as well. Choosing the correct drill bit size may seem like a challenge at first, but it gets easier the more you use your drill.

Low carbon steel, often referred to as plain steel or mild steel, cannot be hardened, but is a very strong material, able to flex under load without damage while offering exceptional performance. This property is referred to as ductility.
