I have these on 2 machines right now. A Haas VF6, and a Hurco with a 5 Axis head. They fit like a glove on both machines and perform as expected. Cleaning the machines is so much simpler now.

Select a drill bit that is the same diameter as the screw's shank. First, select a drill bit that looks as close as possible to the correct size. Then, hold the drill bit behind the screw. If you cannot see the drill bit behind the screw, the drill bit is the correct size.

Drilling a pilot hole—sometimes called pre-drilling—isn't necessary if the material is soft enough to screw into directly without damaging the material. But in most cases, pre-drilling a pilot hole is beneficial.

If you're concerned about the screw head splitting the material, chuck in a countersink bit. If the countersink's drill bit is the correct bit size for the pilot hole, you'll be able to drill the countersink and the pilot in one process.

The drill bit should be the same diameter as the screw's shank—not including the screw threads. The shank is the screw's inner core or its shaft.

With the drill still slowly rotating, withdraw the bit from the hole. Be careful to keep the drill straight to avoid widening the hole. Clear splinters from around the hole before driving the screw.

Open the drill's keyless chuck by turning it counterclockwise. The chuck collets, or the three metal arms, will open up. Insert the drill bit. Turn the keyless chuck clockwise to tighten the bit. Make sure that the drill bit is not crooked or misaligned in the collets.

Place the tip of the drill bit on the mark. Start the drill slowly, applying light pressure to the drill. Increase the speed or pressure on the drill only when needed. Drill the pilot hole as deep as the length of the screw.

I have had our chip guards for over 6 months and love them. They were very easy to install and cut to fit around my vises. If you ever need to add hold downs to the table its very easy to pull up and cut them to fit. They make cleaning the machine so much easier than before, no chips stuck underneath our vises for months. I won't operate another machine without these covers.

Another way to split materials is by attempting to sink the head of the screw into the material. The force of the screwhead (especially a bugle-head screw) will often split the material. Remedy this by cutting out a cone-shaped depression with a countersink bit.

I am very pleased with the service and the product ! I used it on a European Mill with 12 mm T-slots . It's a little tight but with some oil it installed beautiful ! I actually have to get some more as it did not cover all what I wanted to ...

For slippery materials, where the drill bit may skate on the surface, use a hammer to lightly tap a sharp object like a nail or a nailset. This creates a shallow hole that will help the drill bit grip the surface better.

Successful turning requires knowledge of many factors, workholding, materials, tooling available, and much more. The following charts, images, and information are geared toward those that are familiar with Lathes in general, but would like to know more.  This is part of broader curriculum we are currently working on.  The Speed and Feed chart is meant to act as a general guide, your results can and often will vary greatly from job to job.  Machining is complicated, only through experience will things begin to feel easier, hopefully this helps accelerate that learning curve.

Choosing the correct size of drill bit to drill the pilot hole is important. If you choose a bit that's too thin, you might end up splitting the wood. If you choose a bit that's too thick, the screw's threads will not grip the wood.

Drilling a pilot hole is often necessary for building projects or when remodeling the home. But do you know how to drill a pilot hole the right way? Selecting the right drill bit and a few other simple drilling techniques are important to drilling the perfect pilot hole.
