Guhring 9002060079400 Jobber Drill Bit 5/16 in Hss

Product Description

The GUHRING 9002060079400 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel (HSS) with a bright finish, it delivers consistent performance across a wide range of materials without the added cost of coated tooling. The bit features a 118-degree cone relief point, a slow spiral flute geometry, and a web-thinned tip that reduces entry force and improves chip evacuation. At 0.3126 inches in diameter and 117 millimeters overall length, it fits standard drill chucks used in both handheld and machine applications. Machinists, maintenance technicians, and general trade professionals install this type of bit regularly.

This bit suits light to medium-duty drilling operations in shop, field, and maintenance environments. The slow spiral flute is particularly well suited for drilling softer materials where chip control matters. Web thinning at the tip improves bite on harder workpieces and reduces walking at the start of the hole. The 5 times diameter flute-to-diameter ratio provides adequate chip clearance for jobber-length applications. It can be used in drill presses, CNC machining centers, or portable hand drills.

Key Features

• High speed steel construction for general-purpose use across a broad range of materials
• Bright finish - uncoated, suitable for standard drilling without heat buildup concerns
• 118-degree cone relief point for clean entry and reduced thrust force
• Web-thinned tip reduces walking and improves penetration on harder stock

• Right-hand cut with 2 flutes - compatible with standard drill drivers and spindle tooling

Compatibility

Designed as an OEM-style jobber-length drill bit compatible with standard drill chucks and spindles accepting a 0.3126-inch round shank. Conforms to DIN specification for jobber-length twist drills.

Installation Notes

A licensed machinist or qualified technician should secure the bit firmly in the chuck before operation, ensuring shank engagement meets tool manufacturer minimums. Always power down or de-energize the drill or machine spindle before changing tooling. Use appropriate workholding to prevent part movement during drilling. Inspect the cutting edges for wear or chipping before each use - a damaged cutting edge can cause bit failure or workpiece damage.
