Cleveland C08717 Taper Length Drill Bit No. 7 Hss

Product Description

The CLEVELAND C08717 is a taper length drill bit designed for general-purpose drilling in metalworking and fabrication applications. Built from high-speed steel with a coated finish, this bit features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip clearance at the cutting edge. It carries a No. 7 wire gauge size, corresponding to a decimal diameter of 0.2010 inches, and delivers a right-hand spiral flute cut. Machinists, tool-and-die workers, and maintenance technicians reach for this bit when standard jobber-length drills fall short and a longer reach is needed without stepping up to a full aircraft-extension bit.

This bit is suited for drilling alloy steel, carbon steel, and cast iron in both shop and field environments. The taper length body provides additional reach compared to a standard jobber drill, making it a practical choice for deep-hole drilling in fixtures, weldments, and structural components where bit deflection must be kept in check. The straight shank seats directly into standard drill chucks without an adapter. No coolant-through capability is present, so flood or mist coolant applied externally is appropriate for extended production runs.

Key Features

• No. 7 wire size, 0.2010 inch diameter with a tight tolerance of +0.0000 to -0.0007 inches
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High-speed steel construction with coated finish for improved wear resistance
• 3.625-inch spiral flute length supports chip evacuation in deeper cuts
• Right-hand cut with regular spiral type for conventional drilling setups
• Straight shank at 0.2010 inch diameter fits standard drill chucks directly

Compatibility

Designed as a general-purpose replacement or stock taper length drill bit for use in alloy steel, carbon steel, and cast iron applications. Meets ASME B94.11M and DIN 340 standards.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with drill press, lathe, or hand-drill operation. Secure the straight shank fully in the chuck and verify runout before beginning a cut. Power down and lock out the machine before changing bits or clearing chips. External coolant or cutting fluid is recommended for ferrous materials to extend tool life and control heat buildup.
