Kennametal 4150214 Carbide Drill Bit 5.20 Mm 140 Deg

Product Description

The KENNAMETAL 4150214 is a screw machine length (stub length) solid carbide drill bit designed for precision drilling in demanding production environments. Built to DIN 6537K specification, it features a 140-degree point angle for reduced thrust and improved centering on entry. The multilayer TiAlN coating provides heat and wear resistance during high-speed machining. At 5.20 mm in diameter with an overall length of 66.00 mm and a flute length of 28.00 mm, this bit is suited for shorter-reach applications where rigidity and chip control are priorities. It is installed and operated by machinists and tooling technicians in CNC and manual drilling setups.

This drill bit is intended for use in screw machine operations, CNC machining centers, and production drilling applications where stub-length rigidity reduces deflection and improves hole accuracy. The straight cylindrical shank at 6.00 mm diameter accepts standard collet chucks and drill holders. The regular spiral flute geometry supports efficient chip evacuation in a range of ferrous and non-ferrous materials. Maximum drilling depth is 20.00 mm, making it appropriate for through-holes and blind-hole operations within that depth range. It is commonly used in metal fabrication, automotive components, and precision parts manufacturing.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-speed drilling
• TiAlN multilayer coating applied at the tip for elevated heat and abrasion resistance
• 140-degree point angle reduces entry thrust and improves self-centering
• Stub (screw machine) length design minimizes deflection for tighter hole tolerances
• Tapered web configuration supports chip clearance and point strength
• Meets DIN 6537K specification for consistent dimensional standards

Compatibility

Designed as a Series B041A-CPG stub-length carbide drill bit fitting standard straight-shank collet chucks and drill holders accepting a 6.00 mm shank diameter, within the 5.00 mm to 6.50 mm drill bit size range per DIN designation.

Installation Notes

Installation and operation should be performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before inserting or removing the bit. Confirm collet or chuck runout is within tolerance before use, as excessive runout will accelerate wear on solid carbide tooling. Do not exceed the maximum recommended drilling depth of 20.00 mm for this stub-length geometry.
