Hertel C.40W.2540 Taper Length Drill 1 in Hss

Product Description

The HERTEL C.40W.2540 is a taper length twist drill bit ground from high-speed steel (HSS) with a black oxide finish. It cuts a 1.0000-inch diameter hole and features a standard 118-degree split point with web thinning for easier penetration and reduced walking on entry. The overall length is 11 inches with a 6.375-inch flute length, making it suited for drilling deeper holes than a jobber-length bit allows. Right-hand spiral flutes evacuate chips efficiently during the cut. This drill is installed and used by machinists, maintenance technicians, and industrial tradespeople working in fabrication, structural, or general metalworking applications.

This drill bit is designed for through-hole and deep-hole drilling in ferrous and non-ferrous metals, as well as plastics and composites where a longer reach is required. The straight-cylindrical shank diameter of 1.0000 inch fits standard drill chucks and milling machine spindles of matching capacity. The tapered web configuration adds rigidity along the flute length, reducing deflection when drilling at extended depth. It is a solid choice for shops and field technicians who need consistent hole quality in heavier-gauge material or thicker structural sections.

Key Features

• 1.0000-inch diameter with matching 1.0000-inch straight-cylindrical shank
• 118-degree standard point angle with web thinning for reduced thrust and cleaner entry
• 11-inch overall length with 6.375-inch flute length for extended reach drilling
• HSS construction with black oxide finish for corrosion resistance and reduced friction
• Right-hand cut with regular spiral flutes for efficient chip evacuation
• Tapered web configuration adds column strength and reduces deflection at depth

Compatibility

Designed as an OEM-style replacement or direct-use taper length drill bit for standard drill chucks, milling machine spindles, and drill press setups accepting a 1.0000-inch straight-cylindrical shank.

Installation Notes

Installation is performed by machinists and maintenance technicians using a drill press, milling machine, or magnetic drill with a chuck rated for 1-inch shank capacity. Secure the shank fully in the chuck and verify runout before beginning the cut. Always power down and de-energize the machine before changing bits. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality.
