Value Collection 01189232 Letter W Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01189232 is a Letter W jobber-length drill bit designed for general-purpose metal drilling in professional shop and field environments. Built from high speed steel (HSS) with an oxide coating, this bit drills a 0.386 inch (Letter W) hole with a standard 118-degree point angle. The two-flute, right-hand spiral geometry provides efficient chip evacuation in ferrous and cast iron workpieces. At 5.125 inches overall length with a 3.75-inch flute length and a straight cylindrical shank, it fits standard three-jaw drill chucks used across machine shop, fabrication, and maintenance trades.

This jobber drill is suited for drilling steel and cast iron in both production and maintenance-repair-operations (MRO) settings. The oxide finish provides a mild level of lubricity and corrosion resistance during light-duty cutting. The web-thinned, tapered-web construction reduces thrust requirements at the point, making it easier to start a hole without a center punch on many ferrous materials. It is sized for operators who need a precise Letter W clearance hole for tap preparation or close-tolerance assembly work.

Key Features

• Letter W diameter — 0.386 inch — within the 0.3500 to 0.4000 inch drill size range
• 118-degree standard point angle with web-thinned, tapered-web construction for reduced entry thrust
• High speed steel (HSS) construction with oxide coating for ferrous material applications
• Regular right-hand spiral flute for positive chip clearing in steel and cast iron
• 3.75-inch flute length and 5.125-inch overall length — standard jobber proportions for drill press or hand drill use
• Straight cylindrical shank at 0.386 inch diameter for direct chuck mounting — no reduction sleeve needed

Compatibility

Designed as a general-purpose jobber-length drill bit for use in ferrous workpiece materials including steel and cast iron; fits any standard drill press, mill, or hand drill with a chuck capacity of 0.386 inch or greater.

Installation Notes

Installation is performed by machinists, tool-and-die tradespeople, pipefitters, and maintenance technicians. Secure the straight shank firmly in a keyed or keyless three-jaw chuck before use, and confirm the shank is fully seated with no runout. Always wear eye protection and secure the workpiece — never hand-hold material being drilled. Use appropriate cutting fluid for steel applications to extend bit life and reduce heat buildup.
