Value Collection 01346972 Taper Length Drill 1.9688 in Hss

Product Description

The VALUE COLLECTION 01346972 is a taper length drill bit designed for production and maintenance drilling where a longer flute than a jobber-length bit is needed without the full reach of a screw-machine length tool. Ground from high-speed steel (HSS) with a black oxide finish, it features a 118-degree standard point angle with web thinning on a tapered web configuration. The 1.9688-inch diameter makes it suitable for large-diameter through-hole work in ferrous and non-ferrous metals. Machinists, tool-and-die tradespeople, and maintenance mechanics are the primary users of this type of tooling.

This taper length drill bit is used in vertical mills, drill presses, and radial arm drills for applications requiring a longer reach than a standard jobber bit. The 3.0000-inch flute length and 6-inch overall length give it clearance for deeper holes in structural steel, plate, and cast iron. The straight cylindrical shank, ground to 3/4 inch, accepts standard drill chucks and collet systems sized for that diameter. It is sold individually and suited for both shop floor production runs and field maintenance operations.

Key Features

• 1.9688-inch diameter with 118-degree standard point for general-purpose drilling
• Web-thinned tapered web reduces thrust and improves chip clearance on entry
• Black oxide finish provides mild lubricity and corrosion resistance during storage and use
• HSS construction handles ferrous and non-ferrous metals at conventional cutting speeds
• Right-hand spiral flute with regular helix evacuates chips efficiently in through-hole applications
• Straight cylindrical shank at 3/4 inch fits standard heavy-duty drill chucks and collet holders

Compatibility

Designed as an OEM-style replacement or standard tooling selection for drill presses, vertical mills, and radial arm drills equipped with a chuck or collet system that accepts a 3/4-inch straight shank.

Installation Notes

Installation and use of large-diameter drill bits of this size should be performed by a qualified machinist or maintenance mechanic. Ensure the machine spindle is fully stopped and locked out before mounting or removing the bit from the chuck or collet. Verify chuck capacity and tighten the shank fully before operation to prevent slippage under the high torque loads generated by a 1.9688-inch diameter cut. Cutting fluid appropriate to the workpiece material is strongly recommended to manage heat at this diameter.
