Cleveland C16784 Taper Length Drill Bit 3/16 in Cobalt

Product Description

The CLEVELAND C16784 is a taper length cobalt drill bit designed for heavy-duty drilling in a wide range of materials. Built to Series 2575 standards, it features a 135-degree split point that self-centers on contact and reduces walking on hard surfaces. The parabolic flute geometry improves chip evacuation and allows faster feed rates compared to standard flute profiles. At 3/16 inches in diameter and 5.75 inches overall length, with a 3.375-inch flute, this bit is suited for deeper reach applications where a jobber-length bit falls short. Licensed tradespeople and metalworking professionals reach for this bit when standard tooling underperforms on tough alloys or layered materials.

This drill bit is well suited for drilling aluminum, brass, carbon steel, cast iron, nickel alloy, plastic, stainless steel, and tool steel. Its cobalt construction and M42 material grade make it especially capable on work-hardening materials like stainless and nickel alloys, where heat buildup is a concern. The taper length body gives additional clearance in deeper holes or fixtures where a standard-length bit cannot reach. This makes it a practical choice for fabrication shops, maintenance technicians, and field service professionals working across mixed material environments.

Key Features

• 135-degree split point self-centers and reduces thrust force on entry
• Parabolic flute profile accelerates chip evacuation and supports higher feed rates
• M42 cobalt construction handles heat buildup in stainless steel and nickel alloys
• Web-thinned, tapered web design reduces cutting resistance through the full depth of cut
• Straight shank fits standard drill chucks without adapters
• Conforms to ASME B94.11M and DIN 340 standards

Compatibility

Designed as a taper length replacement or upgrade bit compatible with materials including aluminum, brass, carbon steel, cast iron, nickel alloy, plastic, stainless steel, and tool steel. Straight shank diameter of 0.1875 inches fits standard three-jaw drill chucks.

Installation Notes

Installation and use should be performed by qualified machinists or tradespeople familiar with rotary cutting tools and safe drilling practices. Secure the workpiece firmly before drilling and verify chuck grip is tight before operation. Use appropriate cutting fluid or coolant when drilling stainless steel, cast iron, or nickel alloys to extend tool life and manage heat. Inspect the cutting edges for wear or chipping before each use and remove the bit from service if damage is found.
