For instance, when designed properly, an insertable combo tool can drill and chamfer possibly three different ways, getting the job done in one pass with one tool, instead of six tools (and six passes). Yes, that custom-made, multiple-feature tool may cost upwards of $3,000, but the savings add up quickly to offset the costs, especially on a high-volume project.

So, how does an up-and-comer join an experienced CNC machine shop? After all, selecting tools is not a skill taught in even the best higher education CNC classes or training sessions. In this case, it’s an example of tribal knowledge: expertise passed down from engineer to engineer, usually within high-end CNC machine shops.

Most CNC tooling can be used in most CNC machines. That doesn’t always mean those machines are the most efficient, however. Engineers and operators know that a greater horsepower machine — with a bigger taper — provides opportunities to use combo tools (mentioned above) that can perform many functions.

How can you evaluate a shop’s capabilities when it comes to selecting CNC tooling without seeing their work on your project? It’s a difficult task. Look for experience first and ask for references. Also, review these three signs that a CNC machine shop knows how to choose the right tools for complex parts.

Whereas large castings require the help of hoists to move them, smaller castings don’t have that challenge. In fact, there may be opportunities for increased efficiency by designing a fixture that can run two or three small parts at the same time on a larger machine. That’s an example of when large machine = large casting doesn’t necessarily hold true.

Harvey is an English name with Germanic origins, representing "battle worthy," a strong and enduring choice for individuals with resilience.

The flaw in that thinking overlooks potential tooling challenges, which not only match the cost of the initial best-case scenario but also include the added expense of wasted time. That’s why high-end, experienced, confident CNC machine shops don’t seriously consider “Plan B” options. Leadership understands the value of immediately selecting high-quality materials and using the best processes to complete a job, staying ahead while the competition chases.

A PCD-tipped drilling tool has approximately 4 times the tool life of a solid carbide tool (2,500 pieces versus 10,000) and can run 25% faster, offsetting the cost difference between the two (around $180 for carbide versus $960 for PCD) and resulting in production savings.

An economical alternative to solid carbide is a steel tool body with brazed carbide inserts, reducing costs up to 75%. Other options include high-speed steel tools and carbide-tipped tools, preferred by smaller CNC machine shops for cost-effectiveness.

have a “Plan B” (less expensive tooling, less powerful machines, etc.). The temptation is to stay competitive by choosing a less expensive option, which usually means the tooling suffers.

The material of the workpiece drives tool selection. For instance, a shop may primarily machine aluminum, ductile iron, and gray iron castings (which describes Stecker Machine), so there are likely favorite CNC machining metal cutting tools for each material. Engineers choose proven standardized tooling first, helping to reduce risk, inventory, and costs.

Engineers in large CNC machine shops may concept and design over ¾ of all tooling needed within that shop. For instance, if the project requires an insertable combo tool, the engineer sends the part print and model to the toolmaker rep and, together, they complete the design. That hands-on connection results in a more reliable overall project. Small CNC machine shops must completely rely on their toolmaker rep for design and engineering expertise.

CNC tooling — drills, mills, taps — are required to machine different features, and there’s standard tooling for each tool type and material. Again using Stecker as an example, we have three different standard 90° square shoulder face mills, one each for machining aluminum, ductile iron, and gray iron. Of these materials, aluminum has the highest machinability, so the aluminum tooling has higher surface feet per minute (SFM) specifications, so they can run faster.

From the list above, performance of the tool is vital, but it’s not the only thing to consider. The experience of your CNC machine shop plays a part. And, cost is also a big factor, which we’ll address below.

Multiple-feature tools can be huge cost- and labor-savers in CNC machining. If multiple tasks — three or four or more — can be completed by one tool, it cranks up cycle time while also reducing the time needed to change out the tooling.

This is a precision milled filing guide that is used to simplify, and perfect, many of the grinding and filing chores needed in knife making. Using this file guide, you can create perfectly even bevels on both sides of a blade, create accurate grip serrations on the top/bottom surface of any blade, create precision tang widths and flush joints for marrying guards and/or bolsters, and can be used for creating fine angles for artistic file working treatments. To use this knife making file guide, start by clamping the blade between the jaws of the file guide. This enables you to precision file both sides of the blade evenly using hand files or even a grinder. The benefits are enormous, as blade bevels start evenly, stick tang shoulders are squared, and hand file angles are much more accurate. This file guide for knife making is made from non-magnetic stainless steel and has carbide contact surfaces (HRC 78) to maximize long performance life. It will not rust when dunked in water (when cooling blades during grinding) and will not stick to steel dust during grinding. The contacts faces are protected by carbide strips (only diamond or other exceptionally hard tools will scratch these). These contact strips are 78 HRC and very hard. (Please note, ceramic belts can and will damage carbide.) This tool is designed for use with hand tools, or standard aluminum oxide belts (if using a grinder). The carbides are 5/32 inches thick and can be replaced if needed. The carbide strips are recessed slightly into the stainless steel base plates for added protection. This way the strips will not be knocked off, or be placed under pressure when clamping a blade in the file guide. This precision file guide accepts up to 2.75 inch wide blades (70 mm), and up to 1.6 inch thick blades (40 mm). It comes with hardened steel guide pins and (2) Allen wrenches for adjustment and maintenance. Specifications Carbide Faced File Guide 5/16 inch thick carbide contact surfaces (HRC 78) All screws are recessed into the  body for easy access on flat platens Accepts up to 2.75 inch (70 mm) wide x 1.60 inch (40 mm) thick blades and guards Guide pins are hardened steel Non-magnetic

Running multiple parts on a pallet saves time by reducing the number of pallet and tool changes per part. For example, running three parts simultaneously, compared to one, saves 1/3 the tool change and pallet change time per part, plus it increases rapid motions between the three parts in the machine center.

Like any vendor partnerships, a toolmaker and CNC machine shop thrive on familiarity. A large shop’s strategic investment in around seven to eight toolmakers — each specializing in specific challenges such as solid carbide, combo tools, PCD-tipped tools — fosters trust and creates benefits (increased buying power, expedited projects, or a willingness to go the extra mile to satisfy a customer). Again, the larger, more experienced CNC shops have the advantage here.

Finding the best efficiency is mostly about selecting the right tool to match the project needs and the machine’s ability and availability to run it. If a machine can run multiple parts at the same time and the operator changes out three instead of one, that’s a no-brainer.

Solid carbide is reliable, yet PCD-tipped tools reach even higher durability. PCD, or polycrystalline diamond, is the hardest modern cutting tool made by sintering diamond particles with a metallic binder.

Specialty, high-end cutting tools are usually selected for high-volume projects, while low-volume jobs use more economy-level tooling. It comes down to economy of scale, with the cost of high-end, feature-specific tooling being justified by the high quantity of parts to be made by that tool.

When engineers determine how a new project will be completed in the shop, they often create a best-case scenario (best tooling, aggressive cycle times, high-end fixturing), and then also
