Harvey Tool 11662-C3 Spotting Drill 1/16 in Solid Carbide

Product Description

The HARVEY TOOL 11662-C3 is a solid carbide spotting drill designed to create precise starter indentations for follow-on drilling operations. It features a 120-degree point angle and an AlTiN coating, making it well suited for general-purpose spotting in a wide range of workpiece materials. The cutting diameter is 0.0625 inches (1/16 inch), with a 1/8-inch straight cylindrical shank and an overall length of 1.5 inches. The spiral flute geometry and right-hand cut orientation are standard for CNC and manual machining setups. Machinists and tool-and-die professionals install this drill in machining centers, CNC mills, and drill presses where accurate hole location is critical.

This spotting drill is intended for general-purpose spotting applications across a broad range of materials including steel, stainless, aluminum, and cast iron. The AlTiN coating improves thermal resistance and extends tool life at higher cutting speeds. With a flute length of 0.186 inches and a web thickness of 0.005 inches, the 11662-C3 is optimized for shallow, accurate spot drilling rather than deep-hole drilling. It is a single-ended tool packaged individually.

Key Features

• 120-degree Harvey Type I point angle for accurate drill spotting and chamfering
• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for improved heat resistance and extended tool life
• Spiral flute, right-hand cut for standard CNC and manual machining setups
• Straight cylindrical shank for compatibility with standard collets and drill chucks
• Compact 1.5-inch overall length suited for tight tooling clearances

Compatibility

Designed as an OEM-style general-purpose spotting drill compatible with standard 1/8-inch collets, ER collet chucks, and keyless drill chucks used in CNC machining centers and manual milling machines.

Installation Notes

Installation and use should be performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before inserting or removing the tool. Ensure the shank is fully seated and the collet or chuck is torqued to the toolholder manufacturer specification. Verify runout with a dial indicator before production use to protect the small-diameter carbide tip from chipping on initial contact.
