Century Drill Tool 11619 Letter S Hss Drill Bit 3 Pack

Product Description

The CENTURY DRILL TOOL CO INC 11619 is a Letter S high speed steel drill bit designed for general-purpose drilling across a range of common materials. Built from premium-grade HSS with a bright finish, this bit features precision-ground 118-degree split points that self-center and reduce walking on entry. The 118-degree point geometry is well-suited for most shop and field drilling tasks, balancing cutting speed with edge retention. Sold in a 3-pack, this bit is compatible with both stationary drill presses and portable handheld drills, making it a practical shop-floor and job-site option for tradespeople and technicians.

Letter S drill bits fall in the letter-size drill series, which bridges standard fractional and number-size drills. This bit is used in metal fabrication, woodworking, and plastic work where a letter-size diameter is required for a specific hole tolerance or tap drill application. The bright finish reduces friction during cutting and helps shed chips in lighter-duty drilling operations. Suitable for use in HVAC, plumbing, electrical, and general mechanical trade work where precise hole sizing is required.

Compatibility

Installation Notes

Letter S drill bits are installed and removed by a licensed or qualified tradesperson using a standard keyed or keyless drill chuck. Secure the workpiece before drilling to prevent rotation. When drilling metal, use an appropriate cutting fluid to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and replace bits that show signs of chipping or dulling to maintain hole accuracy.
