Guhring 9006510115100 Jobber Drill Bit 29/64 Hss Tin

Product Description

The GUHRING 9006510115100 is a jobber length drill bit designed for general-purpose drilling in ferrous and cast materials. Built from M2 high speed steel with a titanium nitride (TiN) finish, it delivers extended tool life compared to uncoated HSS bits. The drill measures 0.4531 inches (29/64 inch) in diameter with an overall length of 5.5906 inches and a flute length of 3.7008 inches. The 118-degree standard point angle suits a wide range of common drilling applications. Manufactured to DIN 338 standards, this bit is a go-to choice for machinists, maintenance technicians, and trade professionals needing a reliable, dimensionally precise jobber drill.

This drill bit is suited for production and maintenance drilling in cast iron and steel workpieces. The straight cylindrical shank fits standard drill chucks found on drill presses, hand drills, and CNC drilling setups. The 5xD flute-to-diameter ratio and regular spiral flute geometry provide good chip evacuation in typical shop and field conditions. The web-thinned, tapered web configuration reduces thrust force at the cutting tip, which is especially useful when working with harder steel alloys. Sold individually, this bit fits single-use replacement needs or supplementing a drill index.

Key Features

• M2 high speed steel construction for durability in ferrous materials
• Titanium nitride (TiN) coating extends wear resistance compared to bare HSS
• 118-degree standard point angle for general-purpose use on cast iron and steel
• Web-thinned tapered web reduces cutting force and improves penetration
• Regular right-hand spiral flute promotes consistent chip removal
• DIN 338 standard construction ensures dimensional conformance

Compatibility

Designed as a general-purpose jobber length drill bit compatible with any standard drill chuck accepting a 0.4531 inch (29/64 inch) straight cylindrical shank. Rated for primary use in cast iron and steel workpieces per DIN 338 specification.

Installation Notes

Install and remove this bit only when the drill press or power tool is fully powered off and secured against accidental startup. Verify chuck jaws are clean and the shank is fully seated before tightening. Secure the workpiece firmly before drilling; unsecured material can grab and rotate when the bit breaks through. This tool does not support coolant-through operation — apply cutting fluid externally when drilling harder steel alloys to manage heat buildup.
