Cleveland C16970 Cobalt Drill Bit 7/16 in 135 Deg Ticn

Product Description

The CLEVELAND C16970 is a cobalt jobber-length drill bit designed for demanding metal drilling applications where standard high-speed steel bits fall short. Built to M42 cobalt material grade, this bit handles hard alloys, stainless steel, and heat-resistant materials without rapid edge breakdown. The 135-degree split point reduces walking on entry, and the TiCN (Titanium Carbonitride) coating adds surface hardness and lubricity to extend tool life in high-cycle production environments. At 5.5 inches overall length with a 4.0625-inch flute, it fits standard drill chucks and drill presses used in fabrication and maintenance shops.

This drill bit is suited for metalworking trades including pipefitters, millwrights, HVAC fabricators, and maintenance machinists drilling through carbon steel, stainless, and similar ferrous materials. The parabolic flute geometry improves chip evacuation in deeper holes, reducing heat buildup and the risk of chip packing. The straight cylindrical shank at 0.4375 inches diameter seats reliably in standard three-jaw drill chucks. It conforms to ANSI specification designations and is sold individually with a minimum order quantity of 5 units.

Key Features

• M42 cobalt construction for durability in hard and heat-resistant metals
• 135-degree split point reduces bit walking and improves hole entry accuracy
• TiCN coating increases surface hardness and reduces friction for longer tool life
• Parabolic flute design promotes efficient chip evacuation in deeper bores
• Web-thinned tapered web lowers thrust requirements and improves cutting efficiency
• Right-hand cut with straight cylindrical shank for standard chuck compatibility

Compatibility

Designed as a jobber-length replacement drill bit for use in standard three-jaw drill chucks, drill presses, and CNC drilling equipment requiring a 7/16-inch diameter, straight-cylindrical shank bit in the 0.4000 to 0.5000 decimal inch size range.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with drill press and hand-drill operation. Ensure the machine is fully powered down and the chuck key is removed before inserting or removing the bit. Secure the shank fully within the chuck jaws and tighten evenly to prevent runout. Use appropriate cutting fluid for the workpiece material to maintain coating integrity and extend bit life.
