OVERVIEW

Precision Engineering for Industrial Hole Alignment

The Walter 01P101 1-1/16" Reamer represents the pinnacle of hole alignment and enlargement technology for the industrial MRO and fabrication sectors. Manufactured in the United Kingdom, this tool is crafted from premium-grade High-Speed Steel (HSS), a material selected for its exceptional hardness, wear resistance, and ability to maintain a sharp cutting edge even under high thermal loads. Unlike standard carbon steel alternatives, the HSS composition allows this reamer to tackle tough materials—including stainless steel, structural steel, and aluminum—without premature dulling or failure.

One of the critical engineering features of this reamer is its shank design. Recognizing the high torque requirements of reaming operations, Walter has equipped the 01P101 with a 1/2" shank featuring three precision-ground flats. This tri-flat geometry creates a positive lock within the jaws of standard drill chucks, effectively eliminating the risk of the tool spinning or slipping during operation. This ensures that the rotational force of the power tool is fully transmitted to the cutting edges, maximizing efficiency and safety for the operator.

The tool's geometry includes a tapered point, which serves as a pilot to guide the reamer into existing, often misaligned, holes. As the tool advances, the spiral flutes engage the material, shaving off excess metal to bring the hole to a precise 1-1/16" diameter. The spiral design also aids in the rapid evacuation of chips, preventing clogging and heat buildup that could compromise the surface finish. Whether used in heavy manufacturing, structural steel erection, or maintenance repair operations, the Walter 01P101 delivers consistent, precise results that meet the rigorous standards of professional engineers and machinists.

FAQ

The Walter 01P101 reamer is manufactured from premium High-Speed Steel (HSS), which offers superior durability and heat resistance compared to standard carbon steel tools.

Yes, provided your drill has a 1/2" chuck capacity. The shank is exactly 1/2" in diameter.

The three flats are designed to provide a secure gripping surface for the drill chuck jaws, preventing the tool from spinning or slipping inside the chuck under high torque.

Absolutely. The High-Speed Steel construction is robust enough to effectively cut and ream stainless steel, as well as mild steel and aluminum.

This reamer is designed to create or enlarge a hole to a final diameter of 1-1/16 inches.

While the reamer is durable, using a cutting lubricant like Walter Coolcut is highly recommended to extend the tool's life and ensure a smoother cut, especially on thicker metals.

No, this reamer is designed for use with rotary drills (pneumatic or electric) with a standard 3-jaw chuck. It is not compatible with 1/4" hex impact drivers.

The tapered tip acts as a pilot, allowing you to easily insert the tool into misaligned or smaller holes and gradually enlarge them to the final size.
