Guhring 9006510051100 Jobber Drill Bit 7 Hss Tin

Product Description

The GUHRING 9006510051100 is a jobber-length twist drill bit designed for general-purpose metal drilling in production and maintenance environments. Built from M2 high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life compared to uncoated HSS. The bit measures 3.3858 inches overall with a 2.0472-inch flute length and cuts a 0.2010-inch diameter hole. The 118-degree standard point angle suits a wide range of ferrous and non-ferrous materials. A web-thinned, tapered web reduces thrust requirements at drill entry. Licensed machinists, tool-room technicians, and mechanical contractors are the typical users.

This drill bit is suited for drilling cast iron and steel in residential and commercial maintenance, light manufacturing, and fabrication applications. The straight-cylindrical shank seats in standard drill chucks without requiring a specialized holder. At 86 millimeters overall length, it fits benchtop drill presses, hand drills, and CNC drilling spindles with standard ER or keyed-chuck tooling. The Series 651 designation follows DIN 338 specification, making it a direct fit wherever a DIN 338 jobber-length drill is called for. Maximum recommended drilling depth matches the flute length at 2.0472 inches.

Key Features

Compatibility

Designed as a DIN 338 jobber-length replacement drill bit for use in standard keyed or keyless drill chucks accepting a 0.2012-inch straight-cylindrical shank. Primary workpiece materials are cast iron and steel.

Installation Notes

Installation is performed by machinists, tool-room personnel, or qualified mechanical technicians. Secure the shank fully in the chuck and verify runout before drilling. Power down the machine and lock out the spindle before changing or inspecting the bit. Use appropriate cutting fluid for steel workpieces to manage heat and extend tool life.
