Cle-line C18077 Jobber Drill Bit Wire Size 24 Hss

Product Description

The CLE-LINE C18077 is a wire gauge size 24 jobber-length drill bit designed for production drilling in steel, cast iron, and similar ferrous materials. It is manufactured from high speed steel (HSS) with a black and gold oxide coating that improves lubricity and surface hardness at the cutting edge. The 135-degree split point geometry allows the bit to self-center on entry, reducing the need for a center punch and minimizing walking on flat or curved surfaces. Overall length is 3.125 inches, with a 2-inch flute length. Decimal diameter is 0.1520 inches. The web-thinned, tapered web design reduces thrust requirements and is well suited for heavy-duty drilling cycles.

This bit fits standard drilling operations on steel and cast iron in fabrication, mechanical contracting, HVAC, and general maintenance environments. The straight cylindrical shank seats in any 3-jaw chuck or drill press collet capable of accepting a 0.1520-inch shank. Right-hand spiral flute configuration ensures chip evacuation in conventional forward rotation. The HSS grade and black/gold oxide finish make it a practical choice where repeated use on hard ferrous stock is expected and coolant-through tooling is not required.

Key Features

• 135-degree split point self-centers on contact, reducing layout time and eliminating walking
• Web-thinned tapered web lowers drilling thrust and extends bit life on steel and cast iron
• High speed steel construction rated for heavy-duty drilling grade
• Black and gold oxide coating improves surface lubricity and corrosion resistance
• Right-hand regular spiral flute promotes efficient chip clearance
• Straight cylindrical shank fits standard 3-jaw chucks and drill press spindles

Compatibility

Designed as an OEM-style jobber drill bit replacement for applications requiring a wire gauge size 24 (0.1520-inch decimal equivalent) straight-shank drill in ferrous materials.

Installation Notes

Installation is performed by licensed machinists, HVAC technicians, electricians, or maintenance mechanics using a standard hand drill, drill press, or magnetic base drill. Secure the shank fully in the chuck and verify runout before drilling to avoid premature wear. No coolant-through capability is present on this bit; apply cutting fluid manually when drilling harder steels to manage heat buildup. Follow shop safety practices and wear appropriate eye protection during all drilling operations.
