Guhring 9024640067000 Jobber Drill Bit 6.7mm Carbide

Product Description

The GUHRING 9024640067000 is a jobber length drill bit engineered for precision drilling in non-ferrous and light alloy materials. Built from solid carbide grade K40, it carries a FIREX coating that reduces friction and extends tool life in production environments. The drill measures 6.7 mm in diameter (0.2638 inches decimal) with a 118-degree faceted point angle and a web-thinned tip geometry that reduces entry force and improves centering accuracy. Overall length is 101 mm (3.98 inches), and the two-flute spiral design promotes efficient chip evacuation. Qualified machinists and toolroom technicians are the primary users of this bit in both CNC and manual drilling operations.

This drill bit is sized within the 6.00 to 7.00 mm range and is rated as a general-purpose tool with a primary workpiece material designation of N, covering aluminum and other non-ferrous metals. The straight-cylindrical shank at 6.7 mm diameter seats securely in standard drill chucks and collets. Flute length is 63 mm (2.48 inches), with a maximum drilling depth of 52.95 mm (2.085 inches), making it well suited for through-hole and blind-hole applications on machining centers, drill presses, and hand-held power tools where controlled depth is maintained.

Key Features

• Solid carbide K40 grade construction for rigidity and wear resistance in non-ferrous materials
• FIREX coating reduces heat buildup and extends cutting edge life
• 118-degree faceted point with web thinning for accurate self-centering and reduced thrust
• Two-flute regular spiral design promotes clean chip evacuation
• Straight-cylindrical shank compatible with standard chucks and collets
• Diameter tolerance of -0.012 to 0.000 mm ensures consistent hole sizing

Compatibility

Designed as a general-purpose jobber length drill bit within the Guhring Series 2464 product line, suited for use in CNC machining centers, drill presses, and manual drilling equipment that accept a 6.7 mm straight-cylindrical shank. Primary workpiece material designation is N, covering aluminum and non-ferrous alloys per DIN specification standards.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or toolroom technicians familiar with cutting tool setup procedures. Ensure the machine spindle and chuck or collet are fully powered down and secured before loading or removing the bit. Verify shank seating depth and runout with a dial indicator before commencing production drilling. Do not exceed the maximum drilling depth of 52.95 mm (2.085 inches) without retracting to clear chips.
