Value Collection 01378165 Size 16 Cobalt Drill Bit 135 Degree

Product Description

The VALUE COLLECTION 01378165 is a screw machine length cobalt drill bit designed for high-speed drilling in hard and abrasive materials. Built to heavy-duty grade, this wire-gauge size 16 bit measures 0.1770 inches in decimal and features a 135-degree split point that reduces walking on entry and requires no center punch on most surfaces. The overall length is 2-3/16 inches, making it suited for work in tight clearances and short-reach applications common in machining, fabrication, and mechanical service work. The straight shank seats directly into standard drill chucks or screw machine spindles. This bit is sold individually with a minimum order quantity of 12 units.

Screw machine length drill bits are used across metalworking, HVAC fabrication, plumbing rough-in, and electrical panel work where a shorter, stiffer bit reduces deflection and improves hole accuracy. The cobalt construction handles stainless steel, hardened alloys, cast iron, and other tough base metals that standard high-speed steel bits struggle with. The right-hand cutting direction is compatible with conventional drill presses, hand drills, and CNC turret setups running standard forward rotation.

Key Features

• Cobalt tool material rated for heavy-duty drilling in hardened and abrasive metals
• 135-degree split point reduces thrust and eliminates center-punch requirement on most surfaces
• Screw machine length body at 2-3/16 inches overall for improved rigidity and reduced deflection
• 1-1/8 inch flute length provides adequate chip clearance for typical hole depths
• Regular spiral flute geometry promotes consistent chip evacuation in through-hole applications
• Straight shank fits standard drill chucks without adapters

Compatibility

Designed as a drop-in replacement or standard-stock bit for any drill press, hand drill, or CNC turret accepting a straight-shank bit in the 0.1500 to 0.2000 inch decimal range.

Installation Notes

Install and remove drill bits only with the drill or machine fully powered down and the chuck key clear of the chuck. Secure the workpiece firmly before drilling to prevent spinning or shifting. Use cutting fluid or coolant appropriate to the base metal when drilling stainless or hardened alloys to extend bit life. Inspect the cutting edges before each use — cobalt bits can chip if used at incorrect feed rates or if the tip contacts hardened scale without adequate pressure.
