Guhring 9055120095000 Taper Length Drill Bit 0.3740 in

Product Description

The GUHRING 9055120095000 is a solid carbide taper length drill bit designed for high-performance drilling in demanding materials. Built to DIN 6537 standards, this Series 5512 drill features a 140-degree split point (SU-type) that promotes self-centering entry, reducing the need for a center punch in most applications. The 7xD flute-to-diameter ratio provides extended reach for deeper holes while maintaining rigidity. Coolant-through capability makes it well suited for high-speed production environments where heat management is critical. This bit is intended for use by machinists, tool-and-die professionals, and CNC operators working in precision manufacturing.

This drill bit is rated for use in a broad range of materials including steel, stainless steel, cast iron, brass, hardened materials, nickel alloy, and titanium alloy. Its web-thinned, tapered web configuration reduces thrust requirements and improves chip evacuation in tough alloys. The straight shank with a diameter of 0.3937 inches fits standard drill chucks and collet holders commonly used in machining centers and drill presses. Applications include through-hole and blind-hole drilling in aerospace, automotive, and general metal fabrication environments.

Key Features

• Solid submicron carbide construction for extended tool life in abrasive and hard materials
• 140-degree SU split point enables self-centering entry without a pilot hole
• Coolant-through design supports high-speed cutting and effective chip removal
• 7xD flute length ratio delivers a maximum drilling depth of 3.179 inches (80.75 mm)
• Web-thinned tapered web reduces axial thrust and improves cutting efficiency
• Right-hand spiral flute geometry provides consistent chip evacuation
• Meets DIN 6537 standard for taper length carbide drills

Compatibility

Designed as a DIN 6537-compliant Series 5512 taper length drill bit suitable for use in machining centers, CNC drill presses, and manual drill presses equipped with standard straight-shank toolholders. Rated for drilling in steel, stainless steel, cast iron, brass, hardened materials, nickel alloy, and titanium alloy.

Installation Notes

Installation and use of this tooling should be performed by qualified machinists or CNC operators familiar with cutting tool setup and speeds-and-feeds selection. Ensure the machine spindle and toolholder are powered down and at a full stop before inserting or removing the bit. Verify that the shank is fully seated and properly clamped in the collet or chuck before initiating a cut. When using coolant-through capability, confirm that coolant supply lines are connected and flow is verified prior to engaging the spindle.
