OVERVIEW

Precision Hole Enlargement with Walter Technology

The Walter 01W955 Multi-Step Reamer is an essential cutting tool designed for industrial professionals who demand precision and efficiency. Engineered by Walter Surface Technologies, a leader in high-performance metalworking solutions, this 3-step reamer is specifically crafted to address the challenges of enlarging and aligning holes in heavy-gauge metals. Unlike standard drill bits that can grab or wander when widening an existing hole, this step reamer utilizes a specialized geometry to shave material away cleanly, ensuring a perfectly round and burr-free finish every time.

This particular model features three distinct cutting steps, covering a diameter range from 5/16-inch up to 1-1/16-inch. This versatility allows operators to handle multiple bolt hole sizes without the downtime associated with changing tools. It is rated for use on metal plates up to 1/2-inch thick, making it a robust choice for structural steel applications, heavy machinery maintenance, and general fabrication. The tool is manufactured from premium High-Speed Steel (HSS), treated to withstand the high temperatures and stress generated during aggressive reaming operations.

One of the standout features of the Walter 01W955 is its shank design. It incorporates a 3-flat shank which ensures a positive lock within the drill chuck, completely eliminating the frustration of the bit spinning under load. Whether you are working with mild steel, stainless steel, or aluminum, this reamer delivers consistent performance. It serves as a bridge between a standard step drill and a heavy-duty bridge reamer, offering the best of both worlds for MRO (Maintenance, Repair, and Operations) environments.

Investing in Walter tooling means investing in longevity and safety. The step design not only cuts efficiently but also helps in de-burring the entry side of the hole as it progresses to the next step. For workshops and field service trucks alike, the 01W955 reduces the inventory of necessary drill bits while increasing on-the-job capability.

FAQ

The Walter 01W955 is designed to drill and ream through metal plates up to 1/2 inch thick.

The tool covers a range starting at 5/16" and ending at 1-1/16". The 3 steps correspond to specific intermediate and final diameters within this range suitable for common bolt clearances.

Yes, Walter step reamers are manufactured from high-quality HSS and are suitable for use on stainless steel, as well as mild steel and aluminum.

Yes, it features a shank with 3 flats to fit securely in standard 1/2" or larger drill chucks without spinning.

While the tool is durable, using a high-quality cutting lubricant (like Walter Coolcut) is highly recommended to extend tool life and improve the cut quality, especially on stainless steel.

Step drills and reamers are difficult to resharpen by hand due to their complex geometry. It is generally recommended to replace the tool once it becomes dull to maintain safety and performance.

This 'reamer' style step drill is optimized for heavy-duty hole enlargement and alignment in thicker materials (up to 1/2"), whereas standard step bits are often limited to thin sheet metal.
