Guhring 9003360036600 Taper Length Drill Bit 0.1440 in

Product Description

The GUHRING 9003360036600 is a taper length cobalt drill bit with a 0.1440 inch diameter, sized to wire gauge #27, and built to DIN 340 standards. It features a 130-degree standard point, parabolic flute geometry, and a web-thinned parallel web design that reduces thrust and improves chip evacuation. The right-hand cut, cylindrical shank fits standard drill chucks without adapters. This is a high-performance tooling designation suited for machinists, tool-and-die workers, and industrial maintenance professionals who need reliable results in demanding materials.

This drill bit is designed for production and maintenance drilling in cast iron, hardened materials, stainless steel, and carbon steel. The cobalt construction provides heat resistance and edge retention when running at higher speeds or drilling abrasive alloys where standard HSS bits fail prematurely. The parabolic flute profile aids chip clearance in deeper holes, making it well suited for through-holes and repetitive production cycles. It is sold individually but requires a minimum order quantity of 10 units per transaction.

Key Features

• Cobalt tool material for heat resistance and extended tool life in abrasive and hardened materials
• 130-degree standard point angle reduces walking and suits a wide range of work materials
• Parabolic flute design with 10xD flute-to-diameter ratio promotes efficient chip evacuation in deeper holes
• Web-thinned parallel web reduces axial thrust and improves point penetration
• Bright/uncoated finish — no coating to interfere with tight-tolerance applications
• Conforms to DIN 340 specification for taper length twist drills

Compatibility

Designed as an OEM-style taper length drill bit for use in standard drill chucks and CNC drilling applications accepting a 0.1441 inch cylindrical shank, consistent with DIN 340 Series 336 tooling.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard drill press, mill, or CNC machining center. Secure the cylindrical shank firmly in a drill chuck or collet before operation and confirm runout is within acceptable tolerance before drilling. De-energize and lock out all equipment before changing tooling per applicable machine safety procedures. Do not exceed recommended speeds and feeds for the work material to avoid premature edge wear or bit failure.
