Guhring 9085100063500 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9085100063500 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding materials. It carries a 0.25 inch (1/4 inch, Letter E) diameter, a 140-degree split point, and a right-hand spiral flute geometry with web thinning for reduced thrust and cleaner entry. The VA point type and coated finish are engineered to extend tool life in abrasive cutting environments. With coolant-through capability, this bit handles heat effectively in high-speed production applications. It is suited for licensed machinists and tool-and-die professionals working on precision components.

This drill bit is engineered for use in screw machine operations and short-hole drilling applications where rigidity and dimensional accuracy are critical. Its primary workpiece material designation is titanium alloy, making it appropriate for aerospace, medical device, and high-strength structural work. The 3xD flute-to-diameter ratio and screw machine length profile provide stability in tight setups and multi-spindle machine configurations. The straight-cylindrical shank with an 8 mm shank diameter fits standard collets and drill chucks used in CNC machining centers and gang-drill fixtures.

Key Features

• Solid carbide construction rated to K40 material grade for hardness and wear resistance
• 140-degree VA point with web thinning reduces walking and lowers entry thrust
• Coolant-through design channels fluid directly to the cutting edge for heat management
• Coated finish extends tool life when drilling titanium alloy and other abrasive materials
• Conforms to DIN 6537 K specification for consistent dimensional tolerances
• 2-flute right-hand spiral geometry promotes efficient chip evacuation in short-hole work

Compatibility

Designed for use in GUHRING Series 8510 high-performance tooling applications with a primary workpiece material designation of titanium alloy. Fits standard straight-cylindrical collets and drill chucks accepting an 8 mm shank diameter.

Installation Notes

Installation and setup should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool holder is secure before loading or unloading the bit. Verify collet or chuck concentricity before running at speed, as runout directly affects hole tolerance and tool life with solid carbide tooling. Always confirm that the coolant-through system is active and delivering adequate flow before beginning the cut.
