Guhring 9014520067500 Carbide Jobber Drill Bit Letter H

Product Description

The GUHRING 9014520067500 is a solid carbide jobber-length drill bit sized to Letter H (17/64 inch, 0.2656 inch decimal) with a 150-degree drill point angle. It runs a 3-flute spiral configuration with a web-thinned, tapered web for self-centering entry and reduced thrust. The shank is straight-cylindrical at 17/64 inch diameter, and overall length measures 2-29/32 inches (2.9063 inches). Built from submicron carbide grade with a bright, uncoated finish, this bit is suited to high-precision drilling applications where rigidity and point accuracy matter. It is installed by machinists and tool-and-die professionals working in manufacturing, maintenance, and fabrication environments.

The 9014520067500 is engineered for use in CNC machining centers, drill presses, and hand-held tooling setups where a jobber-length solid carbide bit is specified. Its 5xD flute-to-diameter ratio and right-hand cut make it appropriate for through-hole and blind-hole work in ferrous and non-ferrous materials. The self-centering point geometry reduces the need for a pilot hole or center punch in many setups. This bit does not include coolant-through capability, so external or flood coolant is the applicable delivery method when cooling is required.

Key Features

• Solid submicron carbide construction for rigidity and wear resistance in demanding materials
• 150-degree split point with web thinning for self-centering entry and reduced walking
• 3-flute spiral design improves chip evacuation compared to standard 2-flute geometry
• Bright, uncoated finish — compatible with a wide range of cutting fluids and coatings applied in-house
• Straight-cylindrical shank fits standard drill chucks without requiring a special holder
• Manufactured to DIN 6539 specification for dimensional consistency and interchangeability

Compatibility

Designed as an OEM-specification replacement or direct-use carbide jobber drill conforming to DIN 6539, Series 1452, suitable for standard straight-shank drill chucks accepting 17/64 inch shanks.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with carbide tooling requirements. Carbide bits are brittle compared to high-speed steel — secure workpieces firmly and avoid side-loading the bit during entry or retraction. Ensure the drill chuck is clean and properly tightened to the correct shank diameter before operation. Apply appropriate cutting fluid or flood coolant externally, as this bit does not support coolant-through delivery.
