Kennametal 4150182 Screw Machine Drill Bit 10.50mm Carbide

Product Description

The KENNAMETAL 4150182 is a stub-length (screw machine length) solid carbide drill bit designed for precision hole-making in demanding machining environments. Built to DIN 6537K standards, this drill features a 140-degree split-point geometry and a TiAlN multilayer coating at the tip for extended tool life in hard or abrasive materials. The 10.50 mm cutting diameter pairs with a 12.00 mm straight cylindrical shank, keeping the bit rigid and concentric in standard drill chucks or collet holders. With an overall length of 102.00 mm and a flute length of 55.00 mm, it delivers a compact profile suited for short-hole applications where rigidity matters more than depth reach. Machinists and CNC operators working in production or job-shop environments are the primary users.

This drill bit is intended for use in CNC machining centers, drill presses, and screw machines requiring tight-tolerance holes in the 9.50 mm to 11.00 mm diameter range. The Series B041A-CPG belongs to a family of stub-length carbide drills optimized for high-speed, high-feed drilling where a short flute length reduces deflection. Maximum drilling depth is 40.00 mm, making it appropriate for through-holes and shallow blind holes in workpieces where stack height is controlled. The right-hand cutting direction is compatible with standard spindle rotation on conventional machine tools.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 140-degree point angle reduces thrust and improves self-centering on entry
• TiAlN tip coating extends tool life in high-temperature cutting conditions
• DIN 6537K specification ensures dimensional consistency and interchangeability
• Tapered web configuration adds core strength at the drill tip
• Straight cylindrical shank fits standard ER collets and drill chucks without adapters

Compatibility

Designed as an OEM-style replacement or production drill for machining operations requiring a 10.50 mm diameter stub-length carbide drill conforming to DIN 6537K. Compatible with machine tool holders accepting a 12.00 mm straight cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the spindle fully stopped and the machine in a safe, locked-out state before tool changes. Confirm the tool holder bore and collet size match the 12.00 mm shank diameter before clamping. Do not exceed the 40.00 mm maximum drilling depth; exceeding this limit risks chip packing and tool breakage. Follow machine tool manufacturer guidelines for speed and feed selection based on workpiece material.
