Cleveland C02906 Jobber Drill Bit Wire 68 Hss 118 Degree

Product Description

The CLEVELAND C02906 is a jobber-length drill bit sized to wire gauge #68, with a decimal diameter of 0.0310 inches. Manufactured from high speed steel (HSS) with a bright, uncoated finish, this bit features a standard 118-degree split point and a fast spiral flute for efficient chip evacuation. A web-thinned, tapered web reduces thrust during entry, making it well-suited for controlled drilling in light-gauge and precision applications. The straight-cylindrical shank measures 0.0310 inches in diameter and seats securely in standard drill chucks and collets. Overall length is 1-3/8 inches, with a 1/2-inch flute length. The bit conforms to ASME B94.11M and ANSI specification designations.

This bit is intended for general-purpose drilling in aluminum and similar non-ferrous or soft materials where a small-diameter, wire-gauge size is required. Typical applications include precision hole placement in sheet metal, instrument panels, electrical enclosures, and light fabrication work. The right-hand cutting direction and fast spiral geometry promote clean entry and exit without coolant. Trade users in HVAC, electrical, and light mechanical trades will find this size useful for pilot holes, rivet prep, and small fastener clearance holes.

Key Features

• Wire gauge #68 diameter — 0.0310 inches — for precision small-hole drilling
• High speed steel construction for durability across general-purpose applications
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Fast spiral, 2-flute design promotes chip clearing without coolant
• Bright uncoated finish — no coating to flake or chip during use
• Conforms to ASME B94.11M and ANSI specification standards
• Diameter tolerance held to -0.0005 to 0.0000 inches for consistent fitment

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill chucks and collets accepting a 0.0310-inch straight-cylindrical shank. Primary workpiece material designation is aluminum; also suitable for other non-ferrous and soft materials in general fabrication contexts.

Installation Notes

Secure the straight-cylindrical shank fully in the chuck or collet before operation and verify runout is within acceptable limits for small-diameter bits. At this diameter, feed pressure should be light and controlled to prevent bit breakage — avoid side loading. Use a center punch or pilot hole to prevent walking on smooth surfaces. Inspect the cutting edges before each use; at 0.0310 inches, even minor edge damage significantly affects hole quality.
