Guhring 9005010035700 Taper Length Drill Bit 0.1405 in Hss

Product Description

The GUHRING 9005010035700 is a taper length drill bit designed for general-purpose drilling in production and maintenance environments. Built from high speed steel with a bright, uncoated finish, this bit features a parabolic flute geometry and a web-thinned tip that reduces thrust and improves chip evacuation. The 130-degree split point provides accurate self-centering entry without a center punch on most materials. With a flute-to-diameter ratio of 10xD and a cylindrical shank, this bit suits both hand-held and machine setups. It is sized at 0.1405 inches in diameter, corresponding to wire gauge size 28, and conforms to DIN 340 standards for taper length geometry.

This drill bit is suited for drilling aluminum alloy and steel in light manufacturing, job shop, and maintenance repair applications. The parabolic flute design promotes faster chip removal in deeper holes, making it effective where standard jobber-length bits would pack chips or require frequent peck cycles. The cylindrical shank fits standard drill chucks and collet systems without modification. Machinists, tool and die workers, and maintenance technicians working with ferrous and non-ferrous materials will find this bit a reliable general-purpose option at the 0.1405 inch diameter.

Key Features

• High speed steel construction for durability across aluminum alloy and steel applications
• Parabolic flute with 10xD ratio promotes efficient chip evacuation in deeper bores
• Web-thinned, parallel web design reduces drilling thrust and improves centering
• 130-degree standard point angle for self-centering entry on most common workpiece materials
• Bright, uncoated finish compatible with standard cutting fluids and dry drilling
• Conforms to DIN 340 taper length specification for consistent geometry and interchangeability

Compatibility

Designed as a DIN 340 taper length replacement drill bit for use in standard drill chucks and collet systems accepting a cylindrical shank at 9/64 inch shank diameter, suitable for general-purpose machine and hand-drill applications in aluminum alloy and steel.

Installation Notes

Installation and use should be performed by machinists or qualified technicians familiar with rotating cutting tools. Secure the cylindrical shank fully in the chuck or collet before operation and verify runout before beginning a drilling cycle. Always reduce spindle speed and apply appropriate cutting fluid when drilling steel to extend tool life. Inspect the web-thinned point for chipping or wear before each use and replace if edge condition is compromised.
