Kennametal 1235769 Solid Carbide Jobber Drill Bit No. 33

Product Description

The KENNAMETAL 1235769 is a solid carbide jobber-length drill bit designed for precision drilling in demanding production environments. Built to DIN 6537L specification, it cuts a 0.113-inch (No. 33 wire gauge) hole with a 130-degree standard point angle that reduces thrust and improves centering on entry. The three-flute spiral geometry, combined with a web-thinned parallel web configuration, promotes efficient chip evacuation and reduces torque load. Finished with a bright coating, this bit suits machinists and tool-and-die professionals who need consistent hole tolerances in ferrous and non-ferrous materials at high feed rates.

This drill bit is suited for CNC machining centers, drill presses, and automated production cells where tight hole tolerances and repeatable results are required. Its straight cylindrical shank, measuring 3/16 inch in diameter, seats directly into standard drill chucks and collet holders without adapters. The compact 2.6-inch overall length makes it appropriate for close-quarter fixture drilling and short-reach setups. Typical applications include drilling pilot holes, through-holes, and precision bore prep in light alloys, cast iron, and hardened steel at the K10 carbide grade rating.

Key Features

• Solid carbide K10 grade construction for wear resistance in high-speed cutting
• Three-flute spiral design improves chip removal versus standard two-flute geometry
• Web-thinned parallel web reduces entry thrust and walking on hard materials
• 130-degree standard point angle for general-purpose drilling across a range of workpiece materials
• Diameter tolerance of +0.0002 to +0.0006 inches ensures consistent, repeatable hole sizing
• DIN 6537L specification compliance supports use in documented manufacturing processes

Compatibility

Designed as an OEM-style jobber-length drill bit compatible with standard drill chucks and collet systems accepting a 3/16-inch straight cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or tooling professionals. Secure the shank fully in a properly sized collet or drill chuck and verify runout before drilling. Always power down the spindle and lock out the machine before changing tooling. Follow applicable shop safety standards and manufacturer feed-and-speed recommendations for the workpiece material; do not exceed the rated maximum drilling depth of 0.84 inches without retracting to clear chips.
