Precision Twist Drill 5997268 QC41P 13/32" HSS Screw Machine Drill Bit Parabolic Flute

The Precision Twist Drill QC41P 5997268 is a 13/32" (0.4063") general purpose heavy-duty screw machine length (stub) drill bit engineered for high-performance drilling in a wide range of materials. Built from High Speed Steel (HSS) with a bright (uncoated) finish, this drill bit delivers reliable performance in production and precision machining environments.

Key Features:

• Heavy-Duty Parabolic Flute Design — large flute space promotes efficient chip evacuation and improved coolant flow to the cutting point
• 135° Radius Split Point — self-centering tip reduces walking, minimizes thrust, and enables faster penetration with no pilot hole required
• Screw Machine (Stub) Length — shorter overall length provides increased rigidity and resistance to deflection for tighter hole tolerances
• High Speed Steel (HSS) Construction — provides excellent wear resistance and toughness across a broad range of materials
• Bright (Uncoated) Finish — improves chip flow when drilling soft or non-ferrous materials
• Straight Round Shank — compatible with standard drill chucks and collets
• Right-Hand Cutting Direction — standard configuration for conventional drilling operations
• 3XD Cutting Depth Capability — allows greater drilling depths in a single pass

Compatible Materials: Alloy steel, plain carbon steel, structural steel, hardened and tempered steel, stainless steel (free machining, ferritic, austenitic, martensitic), aluminum (alloyed and unalloyed), brass, bronze, copper, titanium, nodular graphite, malleable cast iron, and more.

The Precision Twist Drill QC41P series is part of the Dormer Pramet family of cutting tools, trusted in aerospace, automotive subcontracting, and general manufacturing since 1952. It is an ideal choice for operators who require consistent accuracy and productivity in high-volume drilling applications.
