Value Collection 01241702 Hss Jobber Drill Bit 1.70mm

Product Description

The VALUE COLLECTION 01241702 is a high speed steel jobber-length drill bit designed for general-purpose drilling in metalworking and fabrication applications. The bit measures 1.70 mm (0.0669 inches) in diameter with an overall length of 51 mm (2.0156 inches) and a flute length of 25 mm (0.9844 inches). The standard 118-degree split point with web thinning reduces walking on entry and lowers thrust requirements at the drill press or hand drill. An oxide coating provides a basic level of surface hardness and lubricity. This is a straight-shank bit turned by machinists, tool and die workers, sheet metal fabricators, and maintenance mechanics.

This bit is suited for drilling steel and cast iron in production and maintenance environments. The 1.70 mm diameter falls within the 0.0500 to 0.1000 inch size range, making it appropriate for pilot holes, tapping preparation, and precision small-diameter through-holes in ferrous materials. The regular spiral flute promotes chip evacuation in standard drilling operations. This bit ships individually and is intended for use in standard drill chucks accepting straight cylindrical shanks.

Key Features

• 1.70 mm (0.0669 inches) diameter with a straight cylindrical shank of matching diameter
• 118-degree standard point angle with web thinning for reduced entry walking
• High speed steel construction for general-purpose ferrous metal drilling
• Oxide coating for basic surface lubricity and corrosion resistance during storage
• Regular spiral flute with tapered web configuration promotes chip clearance
• Right-hand cutting direction for use with standard drill press and hand drill rotation

Compatibility

Designed as a general-purpose jobber drill bit for drilling steel and cast iron workpieces. Compatible with any standard drill chuck or collet accepting a 0.0669-inch straight cylindrical shank.

Installation Notes

Installation is performed by machinists and fabricators using a drill press, CNC machine, or hand drill. Secure the straight shank firmly in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend tool life, noting that this bit does not support coolant-through delivery. Inspect the cutting edges for wear before each use, as small-diameter bits are susceptible to breakage under side load or excessive feed pressure.
