Seco 02898331 Screw Machine Drill Bit 3/8 in Carbide

Product Description

The SECO 02898331 is a screw machine length drill bit designed for high-performance drilling in metal, composite, and hard material applications. Built from solid carbide, this bit delivers superior wear resistance and heat tolerance compared to high-speed steel alternatives. It features a 140-degree standard point angle with web thinning for reduced thrust and cleaner entry, and a straight-cylindrical shank measuring 0.3937 inches in diameter. The overall length is 3.50 inches (89 mm), making it well suited for short-reach, high-rigidity setups on CNC machining centers, drill presses, and screw machines. Coolant-through construction supports extended tool life in production environments.

This drill bit is intended for use in production machining operations where tight tolerances and consistent hole quality are required. The SD1103A series is a universal-performance tool appropriate for a wide range of workpiece materials. Its screw machine length profile keeps the tool compact and rigid, reducing deflection in close-clearance fixtures and multi-spindle setups. Machinists and tool-and-die professionals working in job shops, production lines, or maintenance environments will find this bit suitable for standard drilling cycles at moderate to high feed rates.

Key Features

• Solid carbide construction for extended tool life and heat resistance
• 140-degree standard point angle with web thinning for reduced entry thrust
• Coolant-through design supports high-feed production drilling
• Right-hand spiral flute with 2-flute geometry for efficient chip evacuation
• Screw machine length (3.50 inches OAL) provides maximum rigidity in short-reach applications
• Straight-cylindrical shank compatible with standard drill chucks and collet holders

Compatibility

Designed as an OEM-style replacement or direct-use screw machine length drill bit suitable for CNC machining centers, drill presses, and multi-spindle screw machines accepting a straight-cylindrical shank of 0.3937 inches diameter.

Installation Notes

Installation and use should be performed by qualified machinists familiar with cutting tool setup and machine operation. Secure the shank fully within the collet or chuck before initiating a cut, and verify spindle runout is within acceptable tolerance for the application. Ensure coolant flow is confirmed before starting coolant-through drilling cycles to prevent premature tool failure. Follow machine manufacturer guidelines and applicable shop safety standards when changing or setting tooling.
