Seco 00059679 Carbide Replaceable Tip Drill 16.67mm SD100

Product Description

The SECO 00059679 is a carbide replaceable tip drill from the SD100 series, designed for precise hole-making in steel workpieces. It features a 16.67mm drilling diameter and a 12.6mm tip height, with a 140-degree included point angle for accurate centering and reduced thrust. The cutting tip is manufactured from solid carbide and coated with TiAlN via a PVD process, providing heat resistance and extended tool life in ferrous applications. Through-coolant capability delivers cutting fluid directly to the cutting zone, helping to clear chips and manage heat in deep-hole operations. This drill is used in CNC machining environments by machinists and tool-and-die professionals.

The 00059679 is suited for production drilling in steel (material code P) across both general machining and precision manufacturing operations. The replaceable tip design allows worn or damaged tips to be swapped without discarding the drill body, reducing tooling cost per hole. The SD100 series is a modular platform, and this drill accepts the P-geometry insert style. Typical applications include through-holes and blind holes in mild steel, alloy steel, and similar P-category workpiece materials on vertical and horizontal machining centers.

Key Features

• Solid carbide replaceable tip in P geometry for rigid, accurate cutting
• TiAlN PVD coating provides thermal resistance and wear protection in steel cutting
• 140-degree included point angle for self-centering entry and reduced thrust force
• Through-coolant design delivers fluid directly to the cutting edge for chip evacuation and heat control
• Modular SD100 series body allows tip replacement without scrapping the shank
• Optimized for steel (P-category) primary workpiece materials

Compatibility

Designed for use with SD100 series replaceable tip drill bodies accepting P-geometry inserts. Primary workpiece material compatibility is P-category steel as specified by the manufacturer.

Installation Notes

Installation and tip replacement should be performed by a qualified machinist following the machine tool manufacturer and SECO tooling assembly guidelines. Ensure the machine spindle is fully stopped and locked out before changing the replaceable tip. Use the recommended torque tool and seating procedure specified in the SD100 series tooling documentation to properly seat the tip in the body. Confirm through-coolant passages are clear and unobstructed before returning the drill to service.
