Precision Twist Drill 5998272 3/16 Inch Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 5998272 is a jobber-length drill bit designed for general-purpose metal drilling in professional trade and shop environments. Built from high speed steel (HSS) with a bright uncoated finish, it features a 118-degree standard point angle and a regular spiral flute with web-thinned geometry for reduced thrust and cleaner entry. The 3/16 inch diameter straight-cylindrical shank pairs with a 3.5 inch overall length, making it compatible with standard drill chucks. Machinists, maintenance technicians, pipefitters, and sheet metal workers commonly reach for this bit when drilling through ferrous and non-ferrous stock.

This bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It fits standard jobber-length applications across fabrication shops, mechanical rooms, and field service work where a reliable general-purpose HSS bit is needed. The Series R10P designation places it within the PRECISION TWIST DRILL family of ANSI-standard jobber bits. Right-hand cut operation is compatible with any conventional drill press, handheld drill, or mill spindle running standard clockwise rotation.

• ANSI-standard jobber length series for consistent sizing across tool inventories

Compatibility

Designed as an ANSI-standard jobber-length replacement or stocking drill bit for use in conventional drill presses, handheld drills, and milling machines fitted with a 3/16 inch or larger chuck capacity.

Installation Notes

Install in a clean, properly sized chuck and tighten securely before operation. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Use appropriate cutting fluid when drilling stainless steel, superalloys, or titanium to extend bit life and manage heat. Inspect the cutting edge for wear before each use and replace when the point shows signs of dulling to maintain hole quality and prevent workpiece damage.
