Titan Usa CD44016 Jobber Drill Bit Letter E 0.2500 in Hss

Product Description

The TITAN USA CD44016 is a jobber-length drill bit sized to Letter E (0.2500 inches) designed for precision drilling in demanding trade and industrial applications. Built from high speed steel (HSS) with a black oxide coating, the bit features a 135-degree split point that self-centers on contact and reduces walking without requiring a center punch. The two-flute, regular spiral design evacuates chips efficiently during through-hole and blind-hole operations. At 4 inches overall length with a 2.75-inch flute and a straight cylindrical shank, it fits standard drill chucks and CNC toolholders without adapters. Right-hand cutting direction is standard for conventional drill press and hand-drill use.

This drill bit is suited for production and maintenance drilling in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It is a practical fit for HVAC fabrication, plumbing rough-in, electrical panel work, and general metalworking where consistent hole tolerance is required. The 0.2500-inch diameter corresponds directly to a 1/4-inch nominal size, making it a common choice for clearance holes, tapping pilots, and conduit knockout preparation. The CD44 series targets professional tradespeople and shop machinists who cycle through jobber bits at volume.

Key Features

• 135-degree split point self-centers and reduces drill walk on hard and layered materials
• High speed steel construction withstands the heat generated in steel, stainless steel, and superalloy drilling
• Black oxide coating reduces friction and provides light corrosion resistance during storage
• Right-hand, regular spiral flute promotes efficient chip evacuation in deep-hole applications up to 2.75 inches
• Straight cylindrical shank fits standard 3-jaw chucks and collet toolholders without modification
• Zero flats on the shank eliminate indexing complications in universal chuck setups

Compatibility

Designed as a standard jobber-length replacement drill bit compatible with any drill press, hand drill, or CNC machine equipped with a chuck or collet accepting a 0.2500-inch straight cylindrical shank.

Installation Notes

Installation and use of this bit should be performed by qualified machinists, maintenance mechanics, or licensed tradespeople familiar with rotating cutting tool safety. Secure the shank fully within the chuck and verify runout before drilling. Always power down the drill or disconnect the machine before changing bits. Use appropriate cutting fluid or coolant on stainless steel and superalloys to extend tool life and maintain hole tolerance, even though the bit does not feature through-coolant capability.
