Guhring 9055140036000 Carbide Drill Bit 0.1417in 140deg

Product Description

The GUHRING 9055140036000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding production environments. Built to DIN 6537 K standards, this Series 5514 bit features a 140-degree split point (SU point type) with web thinning for fast, accurate starts with minimal walking. The 0.1417-inch diameter and right-hand spiral flute geometry are optimized for tight-tolerance holes in ferrous materials. Submicron carbide grade construction provides the hardness and wear resistance needed for high-cycle machining operations.

This drill bit is rated for use in cast iron and steel workpieces, making it well suited for CNC machining centers, screw machines, and automated drilling operations in metalworking shops and precision manufacturing environments. The screw machine length format offers a compact, rigid profile ideal for high-accuracy applications where longer bits would introduce deflection. The straight-cylindrical shank fits standard drill chucks and collets without modification. No coolant-through capability means this bit is intended for external coolant or dry cutting setups.

Key Features

• Solid submicron carbide construction for extended tool life in ferrous materials
• 140-degree SU split point with web thinning reduces thrust and improves hole entry accuracy
• DIN 6537 K specification with parallel web configuration for consistent chip evacuation
• Regular spiral flute, 3xD flute-to-diameter ratio, maximum drilling depth of 0.575 inches (14.60 mm)
• Coated finish for improved surface lubricity and heat resistance
• Right-hand cut, straight-cylindrical shank compatible with standard tooling

Compatibility

Designed as a high-performance OEM-style replacement or upgrade for screw machine length carbide drill bits used in cast iron and steel drilling applications within the 0.1000 to 0.1500 inch diameter range per Series 5514 specifications.

Installation Notes

Installation and use of this bit should be performed by qualified machinists familiar with carbide tooling practices. Secure the straight-cylindrical shank firmly in a collet or drill chuck rated for the operating RPM before use. Carbide tooling is brittle and should never be subjected to side loading or interrupted cuts beyond the tool design rating. Verify machine spindle runout is within tolerance before use to avoid premature chipping or tool failure.
