Guhring 9055100035700 Screw Machine Drill Bit 0.1405 in

Product Description

The GUHRING 9055100035700 is a solid carbide screw machine length drill bit engineered for high-performance drilling in cast iron and steel. It carries a 140-degree split point (SU point type) with web thinning for fast, accurate penetration and reduced thrust. The straight-cylindrical shank measures 6.00 mm in diameter and accepts standard drill chucks and collet holders. With a 2-flute spiral configuration and coolant-through capability, this bit handles demanding production drilling cycles where heat management and chip evacuation are critical. Licensed machinists, tool and die shops, and CNC operators routinely use this bit for tight-tolerance work.

This drill bit is sized at 9/64 inches (wire size 28, decimal 0.1405 inches) and is suited for screw machine operations, CNC machining centers, and manual drilling fixtures where a short, rigid tool is preferred. Primary workpiece materials are cast iron and steel. The flute-to-diameter ratio is 3xD, with a maximum drilling depth of 18.00 mm and a flute length of 20.00 mm. Overall length is 62.00 mm. The parallel web configuration and web-thinned geometry support consistent hole quality at production volumes. This bit conforms to DIN 6537 K specification.

Key Features

• Solid carbide submicron grade construction for extended tool life in ferrous materials
• 140-degree SU split point with web thinning reduces walking and entry thrust
• Coolant-through design supports internal coolant delivery for deep-hole heat control
• 2-flute regular spiral geometry promotes efficient chip evacuation
• Screw machine length (short series) provides added rigidity for precision boring
• Diameter tolerance of +0.004 to +0.016 mm for consistent, repeatable hole sizing
• Conforms to DIN 6537 K standard

Compatibility

Designed as an OEM-style replacement and production-use drill bit for CNC machining centers, screw machines, and manual drill presses requiring a straight-cylindrical shank solid carbide bit in the 0.1000 to 0.1500 inch diameter range, per Series 5510.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with carbide tooling handling. Secure the straight-cylindrical shank fully in a collet, drill chuck, or toolholder rated for the intended RPM and feed before operation. Carbide is brittle — avoid lateral loading, interrupted cuts beyond the tool rating, or dropping the bit on hard surfaces. When using coolant-through capability, verify that the machine spindle and toolholder are configured for internal coolant delivery before engaging the coolant circuit.
