Cleveland C01495 3/16 in Left Hand Jobber Drill Bit Hss

Product Description

The CLEVELAND C01495 is a jobber-length twist drill bit designed for left-hand cutting applications in general-purpose machining and metalworking. Built from high-speed steel with a bright uncoated finish, it measures 3/16 inch (0.1875 inch) in diameter with a 3-1/2 inch overall length and a 2-5/16 inch flute length. The 118-degree standard point angle and web-thinned, tapered web configuration support clean entry and efficient chip evacuation. Two spiral flutes with a regular helix promote consistent cutting performance. Machinists, tool-and-die workers, and maintenance technicians use this bit for through-hole drilling and general metalwork where left-hand rotation is required.

The C01495 is suited for use in left-hand drill applications, including broken fastener extraction setups where a left-hand bit engages the workpiece and backs out a seized screw or stud during the drilling process. Primary workpiece material is aluminum, making it appropriate for light-metal fabrication and repair work in production and field-service environments. The straight-cylindrical shank seats securely in standard Jacobs-style chucks and collet holders. Series 2006 design conforms to ASME B94.11M and ANSI specification standards, confirming dimensional consistency across the production run.

Key Features

• Left-hand cutting direction for reverse-rotation drilling and broken fastener removal
• High-speed steel construction provides durability across general-purpose metalworking tasks
• 118-degree standard point angle with web-thinned tapered web for clean entry and reduced thrust
• Bright uncoated finish maintains original tolerance range of -0.0007 to 0.0000 inch on diameter
• Straight-cylindrical shank at 0.1875 inch diameter fits standard drill chucks and collets
• Conforms to ASME B94.11M and ANSI specification for consistent dimensional compliance

Compatibility

Designed as an OEM-style replacement and general-purpose left-hand jobber drill bit for use in standard drill chucks and collet systems accommodating a 3/16 inch straight shank, consistent with ASME B94.11M dimensional standards.

Installation Notes

Installation is performed by machinists or maintenance technicians using a left-hand-capable drill press, reversible hand drill, or CNC spindle set to reverse rotation. Ensure the chuck or collet is fully tightened to the straight-cylindrical shank before operation. When using for broken fastener extraction, center-punch the fastener before drilling to prevent bit walking. Do not use this bit in a right-hand-only drill without confirming the machine supports reverse rotation.
