Guhring 9024640011000 Carbide Drill Bit 1.1 Mm Firex

Product Description

The GUHRING 9024640011000 is a jobber length drill bit designed for precision drilling in non-ferrous materials, particularly aluminum. Built from K40-grade solid carbide and finished with a FIREX coating, this bit delivers consistent performance in tight-tolerance applications. The 118-degree faceted point and web-thinned tip promote clean entry and reduce thrust force on breakthrough. At 1.1 mm in diameter with a 36 mm overall length (approximately 1.42 inches), it is sized for fine-detail drilling where accuracy is critical. Licensed machinists, tool-and-die technicians, and precision fabricators are the primary installers of this type of bit.

This drill bit is suited for use on CNC machining centers, drill presses, and precision hand-held drilling equipment where small-diameter, high-accuracy holes are required. The 5xD flute-to-diameter ratio supports chip evacuation in shallow-to-moderate depth applications. It is rated for a maximum drilling depth of 12.35 mm (approximately 0.49 inches) and is well matched to aluminum, non-ferrous metals, and similar workpiece materials classified under material code N. The straight-cylindrical shank fits standard precision collets and drill chucks designed for metric tooling.

Key Features

• K40-grade solid carbide construction for rigidity and wear resistance in non-ferrous applications
• FIREX coating reduces friction and extends tool life in aluminum and similar materials
• 118-degree faceted drill point for accurate self-centering and clean hole entry
• Web-thinned design reduces axial thrust and improves chip flow at the tip
• Right-hand spiral flute with regular spiral type promotes efficient chip evacuation
• Straight-cylindrical shank compatible with standard metric collets and precision chucks

Compatibility

Designed as an OEM-style jobber length drill bit conforming to DIN specification standards, suitable for use in precision drilling setups that accept 1.1 mm straight-cylindrical shank tooling.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tool technicians familiar with small-diameter carbide tooling. Always power down and lock out the machine spindle before changing tooling. Carbide bits are brittle and should not be used at feed rates or speeds outside the tool manufacturer recommendations for the workpiece material. Inspect the cutting edges before each use and do not force a chipped or worn bit.
