Guhring 9007320035000 Jobber Drill Bit 3.5mm Carbide

Product Description

The GUHRING 9007320035000 is a jobber-length drill bit designed for precision drilling in aluminum and other non-ferrous materials. Built from solid carbide with a bright, uncoated finish, it delivers consistent performance in general-purpose machining applications. The bit features a 118-degree faceted point angle with web thinning to reduce thrust and improve chip flow at entry. At 3.5 mm in diameter with a 70 mm overall length and a 39 mm flute length, it fits standard CNC machining centers and manual drill presses with a straight-cylindrical shank. This tool is installed and used by machinists and tooling professionals working in production or maintenance environments.

This drill bit is suited for drilling aluminum, non-ferrous metals, and similar workpiece materials where solid carbide tooling provides a rigidity and wear-resistance advantage over high-speed steel. The Series 732 design follows DIN specification standards, making it a familiar fit in shops that source tooling to metric standards. The 5xD flute-to-diameter ratio supports moderate-depth holes without excessive deflection. It is a single-piece, right-hand-cut tool appropriate for use in both CNC and manual drilling setups requiring tight diameter tolerances.

Key Features

• Solid carbide construction provides rigidity and wear resistance for non-ferrous machining
• 118-degree faceted point angle with web thinning reduces entry thrust and improves centering
• Bright, uncoated finish suitable for aluminum and primary workpiece material code N applications
• Straight-cylindrical shank at 3.5 mm diameter fits standard collets and drill chucks
• Regular spiral flute geometry with 5xD ratio supports chip evacuation in moderate-depth holes
• DIN specification Series 732 with h8 diameter tolerance for consistent fit across metric toolholding systems

Compatibility

Designed as a general-purpose jobber-length drill bit conforming to DIN specification standards, compatible with standard straight-shank collets, drill chucks, and toolholders accepting a 3.5 mm cylindrical shank in CNC machining centers and manual drill presses.

Installation Notes

This drill bit is installed by machinists or tooling technicians into a compatible collet or drill chuck. Ensure the machine spindle is fully stopped and the tool is secured to the full recommended grip depth before operation. Verify runout with a dial indicator when tolerance-critical work is required. Follow applicable shop safety procedures and machine manufacturer guidelines for RPM and feed rate settings appropriate to the workpiece material.
