Seco 00059685 Replaceable Drill Tip 0.7283in 18mm 140deg Tialn

Product Description

The SECO 00059685 is a replaceable drill tip from the Crownloc series, designed for use in modular indexable drill systems. It features a solid carbide construction with a TiAlN coating applied via a PVD process, delivering hardness and heat resistance suited to demanding machining environments. The tip measures 0.7283 inches (18.00 mm) in cutting diameter and carries a 140-degree included point angle with a standard point type. It is held in place by a clamp-style insert holding method and uses a helical, regular-spiral flute configuration with two flutes. Machinists and tooling technicians install this tip in compatible Crownloc drill bodies.

This tip is rated for use on steel, stainless steel, cast iron, and hard materials, corresponding to ISO workpiece material codes P, M, K, and H. It is well suited for production drilling operations in aerospace, automotive, and general metalworking applications where consistent hole geometry and tool life are priorities. The functional length is 0.4345 inches, the flute length is 11.00 mm, and the height is 0.5669 inches (14.00 mm). Coolant-through capability is not included in this tip configuration.

Key Features

• Solid carbide substrate for rigidity and wear resistance in ferrous and hard materials
• TiAlN coating via PVD process for elevated heat resistance and extended tool life
• 140-degree standard point angle reduces thrust force and improves centering
• Two helical flutes with regular spiral geometry for chip evacuation
• Clamp-style insert holding method for secure, repeatable seating in Crownloc drill bodies
• Rated for ISO material groups P (steel), M (stainless steel), K (cast iron), and H (hard materials)

Compatibility

Designed as a replacement tip for Crownloc series modular drill bodies. The ISO number for this tip is SD100-18.50-P. Verify body compatibility against the Crownloc system documentation before ordering.

Installation Notes

Installation is performed by tooling technicians or machinists on a bench or at the machine, with the spindle fully locked out before tip exchange. Use the appropriate clamp torque tool specified by the drill body manufacturer. Inspect the seating pocket for chips or debris before installing the tip, as contamination can affect runout and tool life. Handle solid carbide inserts with care to avoid chipping the cutting edges.
