Titan Usa SD92554 Reduced Shank Drill Bit 27/32 in Hss

Product Description

The TITAN USA SD92554 is a reduced shank twist drill bit designed for drilling through metal and other hard materials where a standard full-shank bit will not fit a 1/2 inch chuck. The bit measures 27/32 inch (0.8438 inch decimal) in cutting diameter with a 1/2 inch reduced shank diameter, allowing it to seat in standard 1/2 inch drill chucks and drill presses. The 118-degree split-point angle suits general-purpose drilling in steel, cast iron, and similar materials. Construction is high-speed steel (HSS) with a bright, uncoated finish. Installation and use is typical for machinists, maintenance mechanics, and metalworking tradespeople who need an oversized hole diameter from a 1/2 inch chuck setup.

The SD92554 belongs to the TITAN USA Series 620 line of reduced shank drill bits. It is suited for use in drill presses, milling machines, and handheld drills equipped with a 1/2 inch chuck. The 3-inch flute length provides adequate chip evacuation for moderate-depth holes in ferrous and non-ferrous metals. The 6-inch overall length (OAL) gives enough reach for most standard production and maintenance drilling applications. This bit ships as a single unit and is intended for professional shop and field use.

Key Features

• 27/32 inch cutting diameter (0.8438 inch decimal equivalent) for oversized hole requirements from a 1/2 inch chuck
• Reduced shank with flat — 1/2 inch shank diameter fits standard 1/2 inch drill chucks without an adapter
• 118-degree drill point angle for general-purpose metalworking applications
• High-speed steel (HSS) construction for durability in ferrous and non-ferrous materials
• Bright/uncoated finish — no additional coating to affect dimensional tolerance
• 3 flats on shank prevent slipping in chuck; 2-flute design promotes chip clearance

Compatibility

Designed as an OEM-style replacement or standard production drill bit for use in any drill press, mill, or 1/2 inch keyed or keyless chuck that accepts a reduced flat shank bit in Series 620 configuration.

Installation Notes

Install and remove only with the drill press or machine fully powered down and the chuck key removed from the chuck. Secure all three flats of the shank firmly against the chuck jaws before tightening to prevent bit walk or slippage under load. Standard shop practices per ANSI B94.11 apply for twist drill usage, speeds, and feeds in metalworking. Wear appropriate eye protection; secure workpieces with a vise or clamp before drilling.
