Guhring 9002050061500 Jobber Drill Bit Letter C Hss

Product Description

The GUHRING 9002050061500 is a jobber-length twist drill bit sized to Letter C (0.2421 inches), ground from M2 high speed steel and finished with an oxide coating for improved lubricity and heat resistance. It features a 118-degree standard point angle with web thinning for easier penetration and reduced thrust. The spiral flute geometry is a regular helix suited for general-purpose drilling in a wide range of materials. Right-hand cutting direction and a straight-cylindrical shank make it compatible with standard drill chucks. Overall length is 101.00 mm and flute length is 63.00 mm. This bit is sold individually and is a common shop staple for machinists, maintenance technicians, and fabricators working in metal, plastics, and wood.

This drill bit is suited for general-purpose production and maintenance drilling in ferrous and non-ferrous metals, plastics, and wood composites. It conforms to DIN 338 specification, which defines the dimensional standards for jobber-length drills widely used in industrial and trade environments. The 5xD flute-to-diameter ratio delivers the chip clearance needed for moderate-depth holes without requiring peck cycles in most applications. Licensed machinists, tool-and-die techs, and sheet metal workers will recognize the DIN 338 geometry as a reliable everyday drill.

Key Features

• Letter C size - 0.2421 inches diameter with a tolerance of +0.000 to -0.022 mm
• 118-degree standard point angle with web thinning for reduced entry thrust
• M2 high speed steel construction with oxide coating for lubricity and heat resistance
• DIN 338 specification - industry-standard jobber-length geometry
• Right-hand cut, regular spiral flute, tapered web configuration
• Straight-cylindrical shank fits standard three-jaw drill chucks

Compatibility

Designed as an OEM-style replacement or direct-use jobber drill conforming to DIN 338 dimensional standards, compatible with any standard drill chuck accepting a 0.2421-inch (6.15 mm) straight-cylindrical shank.

Installation Notes

This bit is installed by a machinist or technician into any drill press, hand drill, or CNC spindle with a chuck rated for the shank diameter. Secure the shank fully in the chuck and verify concentricity before drilling. Use appropriate cutting fluid for ferrous metals to extend tool life and maintain dimensional accuracy. Never force a dull bit - regrind or replace when thrust increases noticeably or hole quality degrades.
