Titan Usa SD94737 Reduced Shank Drill Bit 37/64 in Hss

Product Description

The TITAN USA SD94737 is a reduced shank twist drill bit machined from high speed steel (HSS) for drilling into ferrous metals, non-ferrous metals, wood, and plastics. The bit carries a 37/64-inch cutting diameter (0.5781 inches decimal) paired with a 1/2-inch reduced shank, allowing it to seat in standard 1/2-inch chucks without requiring a larger chuck capacity. A 118-degree split point angle provides positive centering on contact and reduces the need for a center punch on most surfaces. The black oxide and straw finish reduces friction and offers moderate corrosion resistance during service. Overall length is 6 inches with a 3-inch flute length, giving adequate chip evacuation clearance on through-hole applications in production or service environments.

This bit is suited for machinists, maintenance technicians, HVAC installers, plumbers, and electricians who need to drill larger-diameter holes through sheet metal, structural steel, pipe hangers, electrical enclosures, or framing with a standard 1/2-inch drill or drill press. The reduced shank design is the key advantage here: operators can run a 37/64-inch hole without a larger chuck or step-up adapter. Series 623 construction targets general-purpose production and field drilling tasks where a dedicated large-diameter HSS bit is needed on a regular basis.

Key Features

• 37/64-inch (0.5781 inches) cutting diameter on a 1/2-inch reduced shank for use in standard 1/2-inch chucks
• 118-degree drill point angle for positive self-centering on flat and curved surfaces
• High speed steel construction maintains cutting hardness under elevated drilling temperatures
• Black oxide and straw finish reduces friction and provides moderate surface protection
• 3-inch flute length promotes efficient chip clearing on deeper cuts
• Reduced shank with 3 flats prevents bit rotation and slippage in the chuck

Compatibility

Designed as a general-purpose OEM-style HSS drill bit compatible with any 1/2-inch keyless or keyed drill chuck, benchtop drill press, or magnetic drill unit accepting a 1/2-inch reduced shank.

Installation Notes

A licensed or qualified tradesperson should confirm workpiece material and bit speed ratings before use. Always secure the workpiece fully before drilling and use appropriate cutting fluid on hard metals to extend bit life. Inspect the cutting edges and flutes before each use and replace any bit showing chipping, cracking, or excessive wear. Disconnect power to any drill press before changing bits.
