Hertel C.40W.2223 Taper Length Drill 0.8750 in Hss

Product Description

The HERTEL C.40W.2223 is a taper length twist drill bit designed for drilling operations that require greater reach than a jobber-length bit without the flexibility of a long-series drill. Manufactured from high-speed steel (HSS) with a black oxide finish, this bit measures 0.8750 inches (7/8 inch) in diameter with a 10-inch overall length and a 6.125-inch flute length. The 118-degree standard point angle and web-thinned, tapered web configuration reduce entry force and improve chip evacuation. Right-hand cut spiral flutes move chips out of the hole efficiently. Machinists, tool-and-die workers, and maintenance technicians use this bit for deep-reach hole making in ferrous and non-ferrous metals.

This drill bit is suited for production and maintenance machining environments where standard jobber-length drills cannot reach the required depth. The straight-cylindrical shank at 0.8750 inches diameter seats directly in standard drill chucks, machine spindles, and collet holders without an adapter. Typical applications include structural steel fabrication, machine shops, and general metal fabrication where through-holes or deep blind holes must be drilled in a single pass. The black oxide finish provides mild lubricity and corrosion resistance during storage and use.

Key Features

• 0.8750-inch (7/8-inch) diameter with matching straight-cylindrical shank for direct chuck mounting
• HSS construction handles the heat and wear demands of metal drilling
• Black oxide finish reduces friction and provides basic corrosion protection
• 118-degree standard point angle for general-purpose metal drilling
• Web-thinned tapered web reduces thrust force required at entry
• 6.125-inch flute length provides extended reach compared to jobber-length equivalents

Compatibility

Designed as an OEM-style replacement or direct-fit taper length drill bit for use in any standard drill chuck or collet system accepting a 0.8750-inch straight-cylindrical shank.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with machine tool operation. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Verify chuck capacity and runout before use, as excessive runout at this diameter can damage the workpiece and reduce bit life. Follow applicable shop safety standards and machine manufacturer guidelines for feed rates and cutting speeds appropriate to the workpiece material.
