Guhring 9007320071400 Jobber Drill Bit Letter K Carbide

Product Description

The GUHRING 9007320071400 is a jobber length drill bit in letter size K, designed for general-purpose drilling in metalworking and fabrication applications. Built from solid carbide with a bright uncoated finish, this bit delivers consistent performance in non-ferrous materials including aluminum. The 118-degree faceted point provides a standard entry angle suitable for a wide range of materials. With an overall length of 109 millimeters and a two-flute spiral design, it is sized for handheld drill chucks, drill presses, and CNC machining centers. The straight-cylindrical shank measures 7.14 millimeters (0.2811 inches) in diameter, fitting standard collets and chucks without modification. Installation and operation are handled by machinists, tool-and-die workers, and CNC operators.

This drill bit is optimized for primary workpiece material code N, indicating non-ferrous metals and plastics such as aluminum, copper, brass, and similar materials. The Series 732 classification places it within a standardized line of carbide jobber drills conforming to DIN specification. The regular spiral type and 5xD flute-to-diameter ratio make it appropriate for through-hole and blind-hole drilling at moderate feed rates. The web-thinned tip reduces thrust force at entry, which is particularly useful when drilling thin-wall or sheet aluminum stock.

Key Features

• Solid carbide construction for wear resistance in non-ferrous materials
• 118-degree faceted drill point with web thinning for reduced entry thrust
• Bright uncoated finish suited to aluminum and other non-ferrous workpieces
• Two-flute regular spiral design promotes efficient chip evacuation
• Straight-cylindrical shank compatible with standard collets and drill chucks
• DIN-specification Series 732 for consistent dimensional conformance

Compatibility

Designed as a general-purpose jobber length drill bit for use in drill presses, CNC machining centers, and handheld power drills equipped with chucks or collets accepting a 0.2811-inch straight-cylindrical shank.

Installation Notes

This bit is installed by machinists and CNC operators following standard tooling change procedures. Secure the shank fully within the collet or chuck to the recommended grip depth before operation. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the bit. Carbide tooling is brittle — avoid lateral loading, interrupted cuts beyond the bit's rated application, or dropping the bit on hard surfaces.
