Guhring 9055110097000 Carbide Jobber Drill 9.7mm

Product Description

The GUHRING 9055110097000 is a solid carbide jobber-length drill bit designed for high-performance drilling in cast iron and steel. Built to DIN 6537L standards, it features a FIREX coating that extends tool life in demanding production environments. The 140-degree split point (SU-style) geometry is web-thinned for self-centering entry without a center punch, reducing setup time on CNC machining centers and production drill presses. With a submicron carbide grade and regular spiral flute, this bit delivers consistent chip evacuation in both through-coolant and standard setups. Coolant-through capability makes it well-suited for deep-hole drilling cycles where heat and chip control are critical.

This drill bit is intended for professional machining applications involving cast iron and steel workpieces, corresponding to material codes K and P. It is a strong fit for job shops, tool rooms, and production machining cells running CNC vertical or horizontal machining centers. The straight-cylindrical shank accepts standard ER collets and drill chucks. A maximum drilling depth of 46.45 mm at a 5xD flute-to-diameter ratio keeps the tool within its designed performance envelope for most through-hole and blind-hole applications in those materials.

Key Features

• Solid carbide construction with submicron grain material grade for durability in hard and abrasive workpiece materials
• FIREX coating provides thermal and wear resistance in ferrous machining
• 140-degree SU point with web thinning enables self-centering entry without a pilot hole
• Coolant-through design supports high-speed, deep-hole drilling cycles with effective chip and heat management
• Regular spiral flute with 2-flute configuration promotes efficient chip evacuation
• Conforms to DIN 6537L and DIN 6535 standards for dimensional consistency and interchangeability

Compatibility

Designed for use in cast iron and steel workpieces (material grades K and P per DIN classification). The straight-cylindrical shank is compatible with standard ER collet chucks and keyed or keyless drill chucks sized for a 10 mm shank diameter.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician. Verify spindle runout and collet condition before mounting to protect tool integrity and dimensional accuracy. Engage coolant flow before the drill contacts the workpiece when using through-coolant capability. Do not exceed the rated maximum drilling depth of 46.45 mm in a single pass without a pecking cycle to manage chip load.
