Value Collection 01391150 Taper Length Drill Bit Hss

Product Description

The VALUE COLLECTION 01391150 is a taper length twist drill bit designed for general-purpose metal drilling applications. Built from high-speed steel (HSS) with a black oxide finish, it offers improved lubricity and basic corrosion resistance compared to uncoated HSS tooling. The 118-degree standard point angle suits a wide range of common work materials including mild steel, aluminum, and plastics. The web-thinned, tapered web construction reduces thrust force at the point and improves chip evacuation. The straight-cylindrical shank fits standard drill chucks without any adapter. At 0.1220 inches (3.10 mm) diameter, this bit handles small-diameter through-hole and clearance hole work in production and maintenance settings.

This drill bit is suited for use in machine shops, maintenance and repair operations, and light fabrication environments. The taper length body provides additional flute length compared to a jobber-length bit, giving more reach for deeper holes in fixtures, weldments, and structural components. Right-hand spiral flutes pull chips up and out of the hole during drilling. General-purpose grade construction makes it appropriate for handheld drill presses, benchtop drill presses, and CNC drilling operations running moderate feeds and speeds.

Key Features

• HSS construction with black oxide finish for improved lubricity and basic corrosion resistance
• 118-degree standard point angle for general-purpose use across common work materials
• Web-thinned tapered web reduces thrust and improves chip evacuation at the cutting point
• Right-hand cut regular spiral flutes for efficient chip removal
• Straight-cylindrical shank fits standard three-jaw drill chucks directly
• Taper length body provides additional reach beyond standard jobber-length bits

Compatibility

Designed as a general-purpose replacement or spare taper length drill bit for use in standard three-jaw drill chucks accepting straight-cylindrical shanks in the 0.1220-inch diameter range.

Installation Notes

Installation is performed by machinists and maintenance technicians. Secure the shank fully in the drill chuck and tighten all chuck jaws evenly before operation. Ensure the workpiece is clamped securely before beginning the cut to prevent walking or grab. Follow shop safety practices and applicable OSHA standards for rotating tooling.
