Cle-line C97309 3/16 Inch Hss Tin Jobber Drill Bit

Product Description

The CLE-LINE C97309 is a jobber length drill bit designed for general-purpose and high-performance drilling in metal, wood, plastic, and similar materials. Built from high speed steel with a titanium nitride (TiN) tip coating, it delivers improved wear resistance at the cutting point compared to uncoated HSS bits. The bit measures 3/16 inch (0.1900 inch) in diameter with an overall length of 3.5 inches and a flute length of 2.31 inches. A 118-degree split point reduces walking on entry and requires no center punch on most surfaces. This bit is suited for use by machinists, maintenance technicians, plumbers, electricians, and HVAC installers who need reliable performance in standard drilling applications.

The C97309 fits standard drill chucks and is appropriate for bench drill presses, hand drills, and drill-driver setups in both shop and field environments. The straight-cylindrical shank at 3/16 inch (0.1900 inch) diameter seats securely in keyed or keyless chucks. The two-flute spiral design with regular helix provides efficient chip evacuation during through-hole and blind-hole drilling. It is built to ASME B94.11M standards and carries an ANSI specification designation, making it suitable for trade and light industrial use where dimensional accuracy and repeatable performance matter.

Key Features

• High speed steel construction with TiN tip coating for extended cutting life at the point
• 118-degree split point for reduced walking and faster penetration without center punching
• Two-flute regular spiral design promotes efficient chip clearing
• Straight-cylindrical shank (3/16 inch) fits standard keyed and keyless drill chucks
• Diameter tolerance of +0.0000 to -0.0007 inch for consistent, accurate hole sizing
• Meets ASME B94.11M standards; ANSI specification designation

Compatibility

Designed as a general-purpose replacement or stock drill bit for any application requiring a 3/16 inch jobber length bit in the 0.1500 to 0.2000 inch drill diameter range, compatible with standard straight-shank drill chucks.

Installation Notes

Installation and use should be performed by qualified tradespeople familiar with rotating cutting tools. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before starting. Use appropriate cutting fluid or coolant on harder materials to extend bit life, even though this bit does not support coolant-through delivery. Inspect the cutting edge before each use and replace the bit if chipping or excessive wear is observed.
