Guhring 9055100110000 Screw Machine Drill Bit 0.4331in

Product Description

The GUHRING 9055100110000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding shop and production environments. Built to DIN 6537K standards, this bit measures 11.00 mm (0.4331 inches) in diameter with a 140-degree split point geometry and a web-thinned tip for reduced thrust and improved hole entry. The straight-cylindrical shank measures 12.00 mm in diameter and seats securely in standard drill chucks or toolholders. With coolant-through capability and a coated finish, this bit is built for continuous duty in production setups where tool life and dimensional accuracy matter. It is installed by machinists and tool-and-die professionals running CNC or manual drilling operations.

This drill bit is suited for screw machine length applications where a compact overall length provides added rigidity. Primary workpiece materials include cast iron and steel. The 3xD flute-to-diameter ratio and regular spiral flute design support efficient chip evacuation in short-hole drilling scenarios. The submicron carbide grade and high-performance classification make this bit a fit for production shops running tight tolerances and high cycle counts on ferrous materials.

Key Features

• Solid carbide construction in a submicron grade for wear resistance in ferrous materials
• 140-degree split point (SU tip) with web thinning reduces entry thrust and improves centering
• Coolant-through design supports high-speed production drilling and extended tool life
• Coated finish for added surface hardness and lubricity
• Parallel web configuration maintains consistent edge strength along the flute length
• Conforms to DIN 6537K specification for dimensional and geometric consistency

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for production drilling applications on cast iron and steel workpieces, compatible with toolholders and drill chucks accepting a 12.00 mm straight-cylindrical shank.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists familiar with CNC or manual drilling equipment. Ensure the machine spindle and toolholder are powered down and fully stopped before inserting or removing the bit. Verify shank seating and runout before beginning a drilling cycle. Coolant-through setups require confirmation that the machine spindle coolant supply is compatible with the toolholder and collet system in use.
