Precise Countersinking for RC Builds

Designed to cut clean 2mm countersunk holes, the Tamiya 74130 Drill Bit is a go-to tool for hobbyists assembling Mini 4WD components and small RC parts. It works well on carbon fiber and FRP, delivering neat, repeatable results that help prevent stress concentrations around screw heads.

Dual Purpose for Plate Refinement

In addition to countersinking, the Tamiya 74130's bit head has sides that can be used to trim or smooth plate edges, making light reshaping tasks quicker during chassis prep. This saves time when fitting plates and tidying up mounting areas.

Can I use this bit in a handheld pin vise?

Yes. The Tamiya 74130 fits standard small drill handles and pin vises that accept this shaft size. Use steady pressure and keep speed moderate when working with FRP or carbon fiber.

What drill speed should I run on carbon fiber?

Use a moderate speed to avoid fraying the fibres. Low to medium rpm with light feed pressure gives the cleanest countersunk finish on carbon fiber and FRP.

How do I maintain the bit for long life?

Keep the bit free of debris and inspect for wear after cutting abrasive materials. A quick clean with a small brush and occasional light lubrication on the shaft will extend service life.
