Guhring 9055110158700 Carbide Drill Bit 5/8 Inch

Product Description

The GUHRING 9055110158700 is a solid carbide jobber length drill bit engineered for precision drilling in demanding production environments. Built to Series 5511 standards and conforming to DIN 6535 and DIN 6537 L, this bit features a 140-degree split-point (SU) tip geometry with web thinning for self-centering entry without a center punch. The straight-cylindrical shank measures 0.6299 inches in diameter and seats securely in standard drill chucks or collet holders. With coolant-through capability and a regular spiral flute design, this bit handles heat and chip evacuation effectively in high-speed applications. Licensed machinists, tool-and-die shops, and CNC operators will find this bit well-suited to high-volume production runs.

This drill bit is designed for primary use in cast iron and steel workpieces, corresponding to material codes K and P. The 5xD flute-to-diameter ratio supports drilling depths up to 2.331 inches (59.20 mm) without step drilling in typical setups. It is appropriate for both manual drill press use and CNC machining center applications where rigid setups and consistent feed rates are maintained. The self-centering SU point eliminates the need for spotting operations on flat or slightly angled surfaces, improving cycle times on production floors.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• 140-degree SU point with web thinning for self-centering, burr-minimizing entry
• Coolant-through design supports internal coolant delivery for heat control in deep-hole applications
• Right-hand spiral flute with regular helix promotes efficient chip evacuation
• 5xD flute ratio allows drilling up to 2.331 inches deep in a single pass
• Conforms to DIN 6535 and DIN 6537 L for dimensional and tolerance consistency

Compatibility

Designed for drilling cast iron and steel workpieces (material codes K and P). Compatible with standard drill chucks and collet systems accepting a 0.6299-inch straight-cylindrical shank. Suitable for CNC machining centers and drill presses with internal or external coolant supply.

Installation Notes

Installation and use should be performed by qualified machinists familiar with carbide tooling requirements. Secure the straight shank fully in a rigid chuck or collet before operation to prevent runout, which can chip carbide cutting edges. Ensure the machine spindle and coolant system are fully stopped before inserting or removing the bit. Follow applicable shop safety standards and machine manufacturer guidelines for feed rate and spindle speed selection appropriate to workpiece material and bit diameter.
