Guhring 9005010084300 Taper Length Drill Bit 0.3320 in

Product Description

The GUHRING 9005010084300 is a taper length twist drill bit designed for general-purpose hole-making in metalworking applications. Built to DIN 340 standards, this high-speed steel (HSS) bit features a 130-degree split point and a parabolic flute geometry that promotes efficient chip evacuation and reduced feed force. The cylindrical shank measures 0.3319 inches in diameter, with the cutting diameter at 0.3320 inches (Letter size Q). With an overall length of 6.5 inches and a flute length of 4.28 inches, it is sized for applications requiring reach beyond what a jobber-length bit provides. Licensed machinists, tool-and-die shops, and metalworking contractors are the primary installers of this tool.

This drill bit is suited for through-hole and deep-hole drilling in aluminum alloy and steel. The parabolic flute profile with a 10xD flute-to-diameter ratio supports deeper cuts with fewer peck cycles. Web thinning at the tip reduces the chisel edge load at drill entry, improving center accuracy and reducing thrust. It is a strong fit for CNC machining centers, drill presses, and manual knee mills where consistent, repeatable hole quality is required in production or maintenance environments.

Key Features

• 130-degree point angle for improved penetration in steel and aluminum alloy
• Parabolic flute geometry with 10xD ratio supports deep-hole chip clearance
• Web-thinned tip reduces entry thrust and improves drill point centering
• Bright/uncoated HSS construction suitable for general-purpose metal drilling
• Cylindrical shank compatible with standard drill chucks and collet holders
• Meets DIN 340 specification for taper length drill geometry

Compatibility

Designed as an OEM-style taper length drill bit per DIN 340 for use in standard cylindrical-shank drill chucks and collet systems rated for 0.3319-inch shank diameters. Rated for drilling aluminum alloy and steel.

Installation Notes

Installation and use should be performed by qualified machinists or metalworking technicians familiar with cutting tool setup and machine operation. Ensure the drill chuck or collet is fully tightened and the shank is fully seated before operation. Disconnect machine power before changing tooling. Do not exceed the machine spindle speed rating or the recommended cutting parameters for the workpiece material.
