Precision Twist Drill 5996576 Jobber Drill Bit 1.5mm Hss

Product Description

The PRECISION TWIST DRILL 5996576 is a jobber-length twist drill bit designed for general-purpose drilling in metal and hard materials. Built from high-speed steel (HSS) with a bright uncoated finish, this bit features a 135-degree split point and a parabolic spiral flute that helps clear chips efficiently during through-hole and plunge drilling operations. The straight cylindrical shank measures 1.50 mm in diameter, matching the cutting diameter for straightforward chuck compatibility. At 40.00 mm overall length with an 18.00 mm flute length, it fits standard keyless and keyed drill chucks used in both handheld and machine tool applications. Installation and use are appropriate for machinists, maintenance technicians, and trade professionals working with ferrous and non-ferrous stock.

This drill bit is rated for use in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. It conforms to DIN 338 specification, making it a recognized standard-dimension tool suitable for production drilling and field maintenance work alike. The QC21PM series is built to heavy-duty grade performance standards while remaining a general-purpose option across a wide range of metalworking applications. The 12xD flute-to-diameter ratio supports adequate chip evacuation in deeper holes relative to the bit diameter.

Compatibility

Designed as a DIN 338 standard jobber-length drill bit suitable for use in handheld power drills, drill presses, and CNC machining centers accepting a 1.50 mm straight cylindrical shank. Rated for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium.

Installation Notes

This bit is installed and used by machinists, maintenance technicians, and trade professionals operating standard drill equipment. Secure the shank firmly in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent rotation. Use appropriate cutting fluid or coolant when drilling stainless steel, superalloys, or titanium to extend tool life. Inspect the cutting edges before each use and replace the bit if chipping or wear is observed.
