Guhring 9055100090000 Screw Machine Drill Bit 9mm

Product Description

The GUHRING 9055100090000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding production environments. Built to DIN 6537K standards, this bit features a 140-degree split point (SU type) with web thinning for reduced thrust and improved hole entry. The 9mm diameter, right-hand spiral flute geometry is optimized for cast iron and steel. Coolant-through design supports high-speed, deep-hole drilling cycles where heat management is critical. With a parallel web configuration and submicron carbide grade, this bit holds tight tolerances and maintains cutting edge integrity through extended production runs. Licensed HVAC techs, machinists, and toolroom professionals will find it well-suited to CNC and screw machine applications.

This drill bit is intended for use in screw machine and short-hole drilling applications on cast iron and steel workpieces. The 3xD flute-to-diameter ratio and screw machine length keep the tool rigid in high-cycle production setups. The straight-cylindrical shank seats securely in standard drill chucks and collet holders with a 10mm shank diameter. It is appropriate for both manual and CNC machine tool spindles where consistent hole quality and diameter tolerance control are required.

Key Features

• Solid carbide construction with submicron carbide grade for long tool life in ferrous materials
• 140-degree SU split point with web thinning reduces entry thrust and improves centering
• Coolant-through capability supports chip evacuation and heat control in deep-hole cycles
• DIN 6537K specification ensures dimensional consistency and interchangeability
• Right-hand spiral flute with regular spiral type for reliable chip flow in steel and cast iron
• Diameter tolerance of +0.006 to +0.021mm for consistent hole sizing

Compatibility

Designed as an OEM-style production drill for use in cast iron and steel applications conforming to DIN 6537K dimensional standards; compatible with standard straight-cylindrical chuck and collet systems accepting a 10mm shank.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with CNC and manual drilling equipment. Ensure the spindle and workholding are fully stopped and power is isolated before inserting or removing the bit from the tool holder. Verify chuck or collet runout is within acceptable limits before starting a production run, as excessive runout accelerates carbide wear. Always use appropriate cutting fluid or coolant-through pressure consistent with the machine tool manufacturer recommendations for carbide tooling.
