Seco 02898329 Screw Machine Drill Bit 9.40mm Carbide

Product Description

The SECO 02898329 is a screw machine length drill bit designed for high-performance drilling in metal and hard materials. Built from solid carbide and coated with TiAlN (titanium aluminum nitride), this bit delivers extended tool life and heat resistance in demanding production environments. The 140-degree point angle promotes aggressive penetration and reduces walking on entry. At 89.00 mm overall length (3.504 inches) with a 9.40 mm diameter, it fits standard right-hand drilling applications where a compact, stub-length tool is needed. Coolant-through capability supports chip evacuation in deep-hole operations.

This drill bit is suited for production machining environments including CNC drilling, mill-turn centers, and drill press work on steel, stainless, cast iron, and similar ferrous and non-ferrous materials. The screw machine length profile makes it a practical choice when rigidity and reduced runout are critical, such as in tight-tolerance hole work on machined components. It is typically used by machinists, tool and die makers, and precision fabricators in both job shop and high-volume production settings.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• TiAlN coating extends tool life by reducing heat buildup and oxidation at the cutting edge
• 140-degree point angle for fast penetration and reduced thrust force
• Coolant-through design aids chip evacuation in deeper holes up to 35.00 mm drilling depth
• Straight cylindrical shank (10.00 mm diameter) compatible with standard drill chucks and collets
• Right-hand cutting, regular spiral flute for reliable chip flow

Compatibility

Designed as an OEM-style replacement or production tooling option for screw machine length drill bit applications requiring a 9.40 mm diameter, straight-cylindrical shank solid carbide bit with TiAlN coating.

Installation Notes

Installation should be performed by qualified machinists following standard toolholding procedures. Verify chuck or collet runout before securing the shank to prevent premature edge wear. Ensure coolant supply lines are functional when using the coolant-through feature. Power down the machine and follow lockout/tagout procedures before changing tooling.
