Seco 02898373 Drill Bit 33/64 in Solid Carbide Tialn

Product Description

The SECO 02898373 is a screw machine length drill bit designed for high-performance drilling in demanding shop and machining environments. Built from solid carbide and coated with TiAlN (titanium aluminum nitride), this bit delivers elevated heat resistance and extended tool life compared to high-speed steel alternatives. It features a 140-degree point angle for reduced thrust and improved centering on entry, and a right-hand, regular spiral flute geometry that promotes efficient chip evacuation. At 4.2126 inches overall length, it fits standard screw machine and CNC drilling setups. Machinists and tool room technicians working with ferrous metals, stainless, and high-temp alloys will find this geometry well suited to their applications.

This drill bit is intended for use in screw machine operations, CNC machining centers, and turret-style drilling setups requiring a compact, stub-length tool. The straight cylindrical shank accommodates standard drill chucks and collet holders. With a flute-to-diameter ratio of 3xD and a maximum drilling depth of 43.00 mm (approximately 1.69 inches), it is optimized for short, precise holes in production environments. Coolant-through capability makes it compatible with through-spindle coolant systems, reducing heat buildup and improving chip flushing in deep-hole applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiAlN coating improves oxidation resistance and extends tool life at elevated cutting temperatures
• 140-degree point angle reduces entry thrust and improves hole location accuracy
• Coolant-through design compatible with through-spindle coolant delivery systems
• Right-hand, regular spiral flute geometry promotes consistent chip evacuation
• Straight cylindrical shank fits standard drill chucks and ER-style collet holders

Compatibility

Designed as a screw machine length replacement drill bit for setups accepting a straight cylindrical shank with a 0.5512-inch (14.00 mm) shank diameter, suitable for drill sizes in the 0.5000 to 0.6000 decimal inch range.

Installation Notes

Installation is performed by qualified machinists or tool room personnel. Ensure the spindle is fully powered down and locked out before changing tooling. Confirm chuck or collet runout is within acceptable tolerance before use, as excessive runout will accelerate carbide edge wear. Do not use this bit in handheld or portable drill applications; it is intended for rigid, machine-held setups only.
