Guhring 9006090035000 Jobber Drill Bit 3.5mm Carbide

Product Description

The GUHRING 9006090035000 is a jobber-length drill bit designed for precision drilling in demanding applications. Built from submicron-grade solid carbide and coated with titanium nitride (TiN), this bit delivers extended tool life and reduced friction in ferrous and non-ferrous materials. It measures 3.5 mm (0.1378 inches) in diameter with an overall length of 2.047 inches and a 150-degree drill point angle. The three-flute spiral configuration promotes efficient chip evacuation, while the web-thinned, tapered web geometry aids in self-centering entry without a pilot hole. Licensed trades and precision machinists specify this bit for tight-tolerance work.

This drill bit is suited for metalworking operations requiring repeatable accuracy and consistent hole geometry. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. With a 5xD flute-to-diameter ratio and a maximum drilling depth of 0.86 inches (21.75 mm), it handles through-hole and blind-hole work in a typical shop or field-service setting. It conforms to DIN 6539 standards, making it a recognized specification for production and maintenance environments alike.

Key Features

• Submicron solid carbide construction for high hardness and wear resistance
• Titanium nitride (TiN) coating reduces friction and extends service life
• Three-flute spiral design promotes faster chip evacuation versus two-flute bits
• 150-degree point angle with web thinning supports self-centering entry
• Straight-cylindrical shank compatible with standard chucks and collet systems
• Conforms to DIN 6539 specification for consistent dimensional accuracy

Compatibility

Designed as a Series 609 jobber-length drill bit conforming to DIN 6539, suitable for use in standard drill chucks and collet holders accepting a 0.1378-inch straight-cylindrical shank.

Installation Notes

Installation and use of carbide drill bits should be performed by qualified machinists or trade professionals familiar with cutting tool setup and machine operation. Ensure the spindle and chuck are fully powered down and secured before inserting or removing the bit. Carbide tooling is brittle and should not be subjected to lateral impact or side loading during setup. Verify feed rate and spindle speed are appropriate for the workpiece material before beginning the cut.
