Cle-line C23355 Cobalt Jobber Drill Bit 7/32 in 135 Deg

Product Description

The CLE-LINE C23355 is a cobalt jobber-length drill bit designed for high-performance drilling in demanding materials. Built to ASME B94.11M standards, this heavy-duty bit features a 135-degree split point that reduces walking and cutting pressure on entry. The gold finish cobalt construction provides heat resistance and extended tool life compared to standard HSS bits. At 3.75 inches overall length with a 2.5-inch spiral flute, it delivers the reach and chip evacuation needed for production and maintenance drilling. A straight cylindrical shank with a diameter of 0.2188 inches seats securely in standard drill chucks. Web-thinned, tapered web geometry reduces thrust requirements across the full flute length.

This bit is suited for drilling aluminum, superalloys, and titanium, making it a go-to choice for aerospace, HVAC fabrication, mechanical contracting, and general metalworking applications. The right-hand, regular spiral flute pattern handles a wide range of metal thicknesses in both handheld and drill-press setups. The Series 1802 designation identifies this as part of a consistent, standardized cobalt line commonly used in production and service shop environments.

Key Features

• Cobalt construction with gold finish for high heat resistance and extended tool life
• 135-degree split point reduces bit walking and lowers entry cutting pressure
• Web-thinned, tapered web reduces drilling thrust across the flute length
• Right-hand, regular spiral flute for efficient chip evacuation
• Straight cylindrical shank fits standard drill chucks without modification
• Meets ASME B94.11M standards for jobber-length drill bits

Compatibility

Designed for use with standard drill chucks accepting a 0.2188-inch straight cylindrical shank. Primary workpiece materials include aluminum, superalloys, and titanium. Coolant-through operation is not supported.

Installation Notes

Install and remove only with the drill powered off and the chuck fully released. Secure the shank fully in the chuck before operation to prevent runout or slippage. For best results in hard superalloys or titanium, use appropriate cutting fluid and reduce feed pressure to avoid work hardening. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
