Precision Twist Drill 5968435 Stub Drill Bit 3/8 in Hss

Product Description

The PRECISION TWIST DRILL 5968435 is a short-length stub drill bit designed for precise, controlled drilling in a wide range of materials. Built from high speed steel (HSS) with a steam oxide finish, this bit features a 135-degree split point for self-centering starts and reduced walking on entry. The straight shank and 3/8-inch diameter make it compatible with standard drill chucks. With a spiral flute design and 2.5XD cutting depth rating, it removes chips efficiently during operation. This bit is suited for professional use in metal fabrication, maintenance, and general trade applications.

This stub drill bit is intended for use in metalworking and industrial trade environments where a shorter overall length provides added rigidity and better hole accuracy. The 89 mm overall length and 43 mm flute length make it well suited for applications where standard-length bits flex or chatter. Applicable materials include aluminum, cast iron, copper, hard materials, magnesium, nickel, stainless steel, steel, synthetic materials, and titanium. It is sold as a single-piece unit.

Key Features

• 135-degree split point for self-centering entry and reduced thrust
• HSS construction with steam oxide finish for corrosion resistance and heat tolerance
• Short stub length increases rigidity and reduces deflection
• 2-flute spiral design promotes efficient chip evacuation
• Right-hand cutting direction, straight shank for standard chuck compatibility
• No coolant channel — dry cutting application

Compatibility

Designed as an OEM-style stub drill bit replacement for use in standard 3/8-inch straight-shank drill chucks across metalworking and industrial trade applications.

Installation Notes

This bit is installed by licensed machinists, electricians, pipefitters, and general trade professionals using standard drill presses or handheld power drills with compatible chuck sizes. Ensure the drill is powered off and unplugged before changing bits. Secure the shank fully in the chuck before operation to prevent slippage or runout. Follow applicable workplace safety standards when drilling hard or exotic materials such as stainless steel or titanium.
