Guhring 9055100051100 Screw Machine Drill Bit 0.201in Carbide

Product Description

The GUHRING 9055100051100 is a solid carbide screw machine length drill bit designed for high-performance metal removal in demanding industrial and trade applications. Built to Series 5510 with a 140-degree split point (SU point type) and web-thinned geometry, this bit delivers fast penetration with reduced thrust. The straight-cylindrical shank measures 6.00 mm in diameter and seats securely in standard chucks and collets. Coolant-through construction supports high-speed drilling cycles by channeling fluid directly to the cutting edge. The right-hand spiral flute configuration evacuates chips efficiently, reducing heat buildup and extending tool life in ferrous materials.

This drill bit is engineered for precision drilling in cast iron and steel, covering a drill bit size range of 0.2000 to 0.2500 inches decimal. The screw machine length format makes it well suited for CNC machining centers, drill presses, and multi-spindle setups where rigidity and short overhang are required. Maximum drilling depth is 0.801 inches (20.34 mm), with a flute-to-diameter ratio of 3xD. The coated finish extends wear resistance under continuous production conditions. Machinists, tool-and-die technicians, and CNC operators working in job shops or production environments are the primary users.

Key Features

• Solid carbide construction rated to High Performance grade for demanding ferrous machining
• 140-degree SU split point with web thinning reduces entry thrust and improves hole accuracy
• Coolant-through design delivers cutting fluid directly to the tip for heat management
• Straight-cylindrical shank (6.00 mm diameter) fits standard toolholders and collets
• Right-hand spiral flute with regular helix promotes efficient chip evacuation
• Conforms to DIN 6537 K specification for consistent dimensional accuracy

Compatibility

Designed as a direct-fit screw machine length drill bit for applications in cast iron and steel. Compatible with any standard drill chuck or collet accepting a 6.00 mm straight-cylindrical shank.

Installation Notes

Installation of this drill bit should be performed by a qualified machinist or CNC technician. Ensure the machine spindle is fully stopped and power is isolated before inserting or removing the bit. Verify chuck or collet runout is within acceptable tolerances before use to protect the carbide cutting edge. Avoid side loading or prying with carbide tooling, as solid carbide is brittle and can fracture under lateral force.
