Guhring 9055100109000 Carbide Drill Bit 0.4291in 140deg

Product Description

The GUHRING 9055100109000 is a solid carbide screw machine length drill bit designed for high-performance drilling in ferrous and hard materials. Built to DIN 6537K standards, this bit measures 10.90 mm (0.4291 inches) in diameter and features a 140-degree split point for accurate starts and reduced thrust. The coolant-through design channels cutting fluid directly to the tip, extending tool life and maintaining chip evacuation in demanding production environments. It is used by machinists, toolroom technicians, and CNC operators in both job-shop and production settings.

This drill bit is engineered for primary use in cast iron and steel workpieces. The screw machine length body keeps the tool compact and rigid, making it well-suited for short-hole drilling on CNC machining centers, drill presses, and turret lathes. The 3xD flute-to-diameter ratio supports drilling depths up to 52.00 mm. Its straight-cylindrical shank diameter of 12.00 mm seats directly into standard chucks and collet holders without adapters in most setups.

Key Features

• Solid carbide submicron-grade construction for extended tool life in hard and abrasive materials
• 140-degree SU point with web thinning reduces entry thrust and improves centering accuracy
• Coolant-through design delivers fluid to the cutting zone for heat management and chip evacuation
• Coated finish enhances surface hardness and wear resistance
• DIN 6537K specification ensures dimensional consistency and interchangeability
• Right-hand spiral flute with parallel web configuration for stable chip flow

Compatibility

Designed as an OEM-specification replacement or direct-fit tooling option for applications requiring a 10.90 mm solid carbide screw machine drill in cast iron and steel per DIN 6537K standards.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with CNC or manual machine operation. Verify spindle speed and feed rate are appropriate for the workpiece material and tool diameter before drilling. Ensure the shank is fully seated and properly clamped in the chuck or collet to prevent runout. Always confirm coolant supply lines are active before engaging the cut when using the through-coolant feature.
