Precision Twist Drill 5968497 Stub Hss Drill Bit 5/32 in

Product Description

The PRECISION TWIST DRILL 5968497 is a short-length, high-speed steel stub drill bit designed for general-purpose metal drilling across a wide range of materials. Built to a 2.5XD cutting depth with a 135-degree split point, it seats quickly and drills without a pilot hole in most applications. The straight shank and spiral flute geometry are optimized for chip evacuation and accurate hole entry. This bit ships individually and is suited for use in standard drill presses, hand drills, and CNC setups where a compact flute length is required for rigidity and reduced deflection.

This stub-length drill bit is appropriate for drilling aluminum, cast iron, copper, magnesium, nickel, stainless steel, carbon steel, synthetic materials, titanium, and hard materials. The short overall length of 55 mm makes it well-suited for confined-space drilling and applications where a standard-length bit would flex or chatter. Licensed machinists, tool-and-die technicians, HVAC fabricators, and industrial maintenance mechanics routinely use stub bits like this one when hole straightness and stability matter more than depth capacity.

Key Features

• 135-degree split point for self-centering entry and reduced thrust force
• High-speed steel construction withstands heat generated in ferrous and hard-material drilling
• Steam oxide finish provides mild corrosion resistance and reduces friction at the cutting edge
• Spiral flute geometry promotes chip clearance during through-hole drilling
• Straight shank fits standard drill chucks without an adapter
• Short stub length increases rigidity and minimizes deflection in precision work

Compatibility

Designed as an OEM-style stub drill bit replacement suitable for use in any standard drill chuck or collet accepting a 5/32-inch straight shank in drill press, hand drill, or CNC drilling applications.

Installation Notes

Secure the shank fully in the chuck and verify runout before drilling. Ensure workpiece is clamped or fixtured — do not hand-hold metal stock during drilling. Use cutting fluid or coolant when drilling stainless steel, titanium, or other hard materials to extend tool life and manage heat. Replace the bit at the first sign of chatter, burning, or reduced cutting performance; dull HSS bits work-harden stainless and nickel alloys.
