Titan Usa CD47527 Jobber Drill Bit Letter Y 27/64 in Hss Tin

Product Description

The TITAN USA CD47527 is a letter-size Y jobber-length drill bit designed for production and general-purpose drilling in non-ferrous metals and similar materials. Built from high speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life compared to uncoated HSS bits. The bit measures 5.375 inches overall length with a 3.9375-inch flute length, giving it reach suitable for through-hole work in typical workpiece thicknesses. The straight-cylindrical shank diameter is 0.4219 inches (27/64 inch), compatible with standard drill chucks. A two-flute, right-hand spiral geometry provides efficient chip evacuation. The 135-degree split-point reduces walking and lowers thrust requirements at entry.

This drill bit is suited for drilling non-ferrous metals including aluminum, brass, copper, and similar materials in light manufacturing, maintenance, and fabrication settings. The 9xD flute-to-diameter ratio supports drilling depths up to 3.9375 inches. It fits standard 3-jaw chucks on drill presses, CNC machining centers, hand drills, and right-angle drills. The CD47 series is designed for shops and trades requiring consistent, repeatable hole sizing in the 0.4000 to 0.5000 inch diameter range.

Key Features

• High speed steel construction with TiN coating for improved wear resistance and lubricity
• 135-degree split point reduces bit walking and entry thrust
• Two-flute right-hand spiral design promotes efficient chip removal
• 5.375-inch overall length with 3.9375-inch maximum drilling depth
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as an OEM-style jobber drill bit for use in standard 3-jaw drill chucks accepting a 27/64-inch straight-cylindrical shank, within the CD47 series for non-ferrous metal drilling applications.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using a drill press, CNC spindle, or portable drill. Secure the shank fully in a properly sized chuck and verify concentricity before operation. Always wear appropriate eye protection and secure the workpiece before drilling. Reduce feed pressure near drill exit to minimize burring and avoid drill deflection.
