Kennametal 1201033 Die Drill Bit 9/32 in Solid Carbide

Product Description

The KENNAMETAL 1201033 is a solid carbide straight-flute die drill bit engineered for high-performance drilling in cast iron and non-ferrous metals. Built to Series K411 standards and conforming to DIN 6537L, this bit measures 0.2813 inches (9/32 inch) in diameter with an overall length of 3.583 inches. The 130-degree split point reduces thrust and prevents walking at entry, while the web-thinned geometry improves chip evacuation. Coolant-through capability via a round coolant-hole channel supports continuous drilling operations in production environments. The bright finish on KF1-grade carbide maintains sharp cutting edges across extended run cycles. Licensed machinists, tool-and-die makers, and precision manufacturing technicians are the primary users of this bit.

This drill bit is suited for precision die work, mold making, and production drilling applications where tight tolerances and clean entry are required. Primary workpiece materials include cast iron and non-ferrous metals such as aluminum and brass alloys. With a maximum drilling depth of 1.59 inches and a flute length of 1.99 inches, it handles through-hole and blind-hole work in fixture plates, die blocks, and machined components. The right-hand cutting direction and two-flute straight design make it compatible with CNC machining centers and manual drill presses running appropriate speeds and feeds for carbide tooling.

Key Features

• Solid KF1-grade carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• 130-degree split point with web-thinned geometry reduces entry thrust and improves hole accuracy
• Coolant-through design with round coolant-hole channel supports high-duty-cycle drilling operations
• Bright finish preserves dimensional accuracy without coating buildup affecting hole tolerance
• Diameter tolerance of +0.0000 to +0.0004 inches suits close-tolerance die and mold work
• DIN 6537L specification ensures dimensional consistency for tool management and replacement sourcing

Compatibility

Designed as an OEM-style precision drill bit for use in CNC machining centers, drill presses, and die-making operations involving cast iron and non-ferrous metals. Confirm spindle collet or chuck accepts a straight shank at the specified shank length of 1.52 inches before installation.

Installation Notes

Installation and use should be performed by qualified machinists or tool-and-die technicians familiar with carbide tooling requirements. Power down and lock out the machine before loading or changing tooling. Carbide bits are brittle and should not be used at feed rates or speeds appropriate for high-speed steel tooling. Use appropriate coolant flow rates when engaging the coolant-through channel to prevent thermal shock to the carbide substrate.
