Value Collection 01244508 4.50mm Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01244508 is a high speed steel (HSS) jobber-length drill bit designed for general-purpose metal drilling in professional and light industrial environments. The bit features a 118-degree standard point angle and an oxide coating that provides basic surface protection and lubricity during cutting. With a 4.50 mm (0.1772 inch) diameter and an overall length of 3.3906 inches, this drill fits standard straight-shank chucks and is sized for common clearance and through-hole work. The web-thinned, tapered web construction reduces entry resistance and helps maintain center on initiation. Machinists, fabricators, and maintenance technicians are the primary users.

This jobber drill is suited for drilling steel and cast iron in general-purpose shop and field applications. The regular spiral flute profile handles a wide range of material hardnesses within its intended workpiece category. The 2.2031-inch flute length provides adequate chip clearance for moderate-depth holes typical of structural and mechanical assembly work. At 4.50 mm diameter, this bit falls within the 4.00-5.00 mm size range commonly used for tapping pre-drill, clearance holes for M5 fasteners, and similar metalworking tasks.

Compatibility

Designed as a general-purpose jobber drill for use in straight-shank chucks accepting 0.1772-inch shank diameter bits, suitable for drilling steel and cast iron workpieces in typical shop and maintenance applications.

Installation Notes

This bit is installed and removed by a licensed machinist, tooling technician, or qualified maintenance professional using a keyed or keyless drill chuck. Secure the shank fully in the chuck before operation and verify the workpiece is clamped or fixtured to prevent rotation. Use appropriate cutting fluid or coolant when drilling steel at sustained depth to extend tool life. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged.
