Seco 02898244 Screw Machine Drill Bit 3mm Carbide Tialn

Product Description

The SECO 02898244 is a screw machine length drill bit designed for high-performance drilling in metal and hard materials. Built from solid carbide with a TiAlN coating, this bit delivers excellent heat resistance and extended tool life in demanding production environments. The 140-degree split point reduces walking and cutting force at entry. With an overall length of 62.00 mm and a 3.00 mm cutting diameter, this is a stub-length tool optimized for rigidity and precision in short-hole applications. It is typically installed by machinists and toolroom technicians running CNC machining centers, drill presses, or multi-spindle equipment.

This drill bit suits general metalworking and precision machining applications requiring tight tolerances in short-depth holes. The screw machine length profile makes it well suited for high-speed production drilling in steel, stainless steel, cast iron, and similar ferrous and non-ferrous workpiece materials. The straight cylindrical shank fits standard drill chucks and collet systems. With a maximum drilling depth of 14.00 mm and a flute-to-diameter ratio of 3xD, this bit is built for efficient chip evacuation in shallow-hole cycles.

Key Features

• Solid carbide construction for superior rigidity and wear resistance versus high-speed steel alternatives
• TiAlN coating provides oxidation resistance and improved performance at elevated cutting temperatures
• 140-degree point angle reduces thrust force and minimizes drill walk on entry
• Coolant-through design supports internal coolant delivery for heat management in deep or high-feed applications
• Regular spiral flute geometry promotes consistent chip evacuation in a range of workpiece materials
• Straight cylindrical shank with 6.00 mm shank diameter fits standard chucks and collet holders

Compatibility

Designed as a screw machine length drill bit for use in CNC machining centers, drill presses, and multi-spindle setups accepting a 6.00 mm straight cylindrical shank; fits within the 0.1000 to 0.1500 decimal inch drill bit size range.

Installation Notes

This drill bit is installed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm chuck or collet bore matches the 6.00 mm shank diameter before securing. Follow machine manufacturer torque and runout specifications for tool holding; excessive runout accelerates wear on carbide tooling.
