Seco 02898272 Solid Carbide Screw Machine Drill Bit 5.1mm

Product Description

The SECO 02898272 is a solid carbide screw machine length drill bit designed for high-precision hole making in demanding machining applications. Built to DIN standards, this right-hand cut bit features a 140-degree split point angle and a web-thinned tip geometry that reduces thrust force and improves centering accuracy at entry. The 5.1 mm cutting diameter pairs with a 6.0 mm straight-cylindrical shank, making it compatible with standard drill chucks and collet holders. Coolant-through capability supports higher feed rates and extended tool life in ferrous and non-ferrous materials. The SD1103A series is rated for universal tool performance across a broad range of workpiece materials.

This bit is suited for CNC machining centers, drill presses, and manual machine tools in manufacturing, toolroom, and maintenance environments. The screw machine length format provides a shorter, more rigid profile compared to jobber-length bits, making it the preferred choice when minimizing deflection in tight setups or shallow-depth hole operations. Maximum recommended drilling depth is 20.0 mm, consistent with the 3xD flute-by-diameter ratio. Machinists, tool-and-die makers, and maintenance technicians working in production or job-shop settings are the primary users of this bit.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-cycle machining
• 140-degree standard point with web thinning for reduced entry thrust and improved self-centering
• Coolant-through design supports higher cutting speeds and chip evacuation
• Straight-cylindrical shank fits standard drill chucks and collet holders without special adapters
• DIN-standard geometry ensures dimensional consistency and interchangeability
• Screw machine length profile provides a stiffer, lower-deflection setup versus jobber-length bits

Compatibility

The SD1103A series is designed as a DIN-conforming screw machine length drill bit suitable for use in CNC machining centers, manual drill presses, and multi-spindle machines accepting a 6.0 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with cutting tool setup. Ensure the machine spindle and chuck or collet are fully powered down and at a complete stop before inserting or removing the bit. Verify shank seating and runout with an indicator before production use, as carbide tooling is sensitive to lateral shock and improper clamping. Do not use this bit as a reamer or apply side-loading forces that exceed the tool design intent.
