MRT1/4X6C

Lockmasters' most popular serrated carbide tipped drill bit. This drill bit is a work horse, it delivers the cutting power you need when drilling most any hardplate. By sharpening the bit in a notched fashion, we end up with more cutting surface as compared to common straight-edge sharpening techniques.

The CHA1/4X6C drill bit has been discontinued. Lockmasters recommends replacing yours with this stronger, more durable, longer lasting drill bit.
