Precision Twist Drill 5998675 Jobber Length Drill Bit

Product Description

The PRECISION TWIST DRILL 5998675 is a jobber-length twist drill bit designed for general-purpose drilling in a wide range of metal and hard materials. Manufactured from high speed steel with a steam oxide coating, it measures 11/16 inch (0.6875 inch) in diameter with an overall length of 7-5/8 inches and a flute length of 5-5/8 inches. The 118-degree standard point angle and web-thinned, tapered web geometry promote clean entry and reduce walking on flat surfaces. Licensed HVAC technicians, plumbers, electricians, and other trade professionals rely on this type of bit for structural drilling tasks on the job site or in the shop.

This bit is suited for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials, covering ISO material codes P, M, K, N, and S. The straight cylindrical shank fits standard drill chucks without adapters. The 2-flute spiral configuration clears chips efficiently during through-hole and deep drilling operations. At a flute-to-diameter ratio of 8xD and a maximum drilling depth of 5-5/8 inches, it handles typical metal fabrication, equipment installation, and mechanical assembly applications found across plumbing, electrical, and HVAC trades.

Installation Notes

Installation of this bit should be performed by a qualified tradesperson familiar with rotary cutting tools and appropriate personal protective equipment including safety glasses and gloves. Secure the shank fully in the drill chuck and verify runout before beginning a cut. Always center-punch the workpiece before drilling hard materials to prevent bit walking. Do not exceed the rated drilling depth of 5-5/8 inches and retract the bit periodically to clear chips and prevent overheating.
