Precision Twist Drill 5996597 13mm Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 5996597 is a jobber-length drill bit designed for general-purpose drilling in metal and hard materials. Built from high-speed steel with a bright, uncoated finish, this bit runs a 135-degree split-point angle that reduces walking on entry and cuts faster through ferrous and non-ferrous stock. The straight-cylindrical shank seats in standard three-jaw chucks without modification. At 5.9449 inches overall length with a 3.9764-inch flute length, it fits conventional drill presses, hand drills, and CNC setups equally well. The parabolic-style spiral flute with web thinning helps clear chips efficiently, reducing heat buildup during extended cuts.

This bit is suited for production and maintenance drilling in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It performs in both shop and field settings where a reliable general-purpose bit is needed across a range of hard materials. The QC21PM series targets heavy-duty applications that demand consistent geometry and chip evacuation without requiring through-coolant capability. Licensed machinists, millwrights, pipefitters, and HVAC fabricators will find this bit at home in everyday metal drilling tasks.

Key Features

• 13 mm (0.5118 inch) diameter with matching straight-cylindrical shank for standard chuck compatibility
• 135-degree point angle reduces bit walking and improves penetration speed on hard materials
• High-speed steel construction rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium
• Web-thinned, tapered-web design improves chip clearance and reduces thrust requirements
• Parabolic spiral flute with 8xD flute-to-diameter ratio supports deeper drilling passes
• Meets DIN 338 specification for jobber-length drill geometry and dimensional tolerances

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard three-jaw drill chuck or collet accepting a 13 mm (0.5118 inch) straight shank. Fits drill presses, hand drills, and CNC spindles within the 12.50 mm to 15.00 mm diameter range of the QC21PM series.

Installation Notes

Installation is performed by machinists, millwrights, or qualified trade professionals operating drill presses, hand drills, or CNC equipment. Secure the shank fully in the chuck and verify zero runout before cutting. Power down and de-energize all equipment before changing or inspecting bits. Do not exceed the rated drilling depth of 3.9764 inches in a single pass without retracting to clear chips.
