Walter Multi-Step Reamer Drill Bit - 5/16" to 9/16"

Heavy-Duty Alignment and Drilling for Fabricators

For professional welders and ironworkers, aligning bolt holes in stacked plates or structural members is a daily challenge. The Walter 01W151 Multi-Step Reamer is designed specifically to address this issue, acting as a game-changer for on-site fit-up and fabrication. This tool combines the versatility of a step drill with the robust cutting capability required for heavy industrial applications.

The standout feature of this reamer is its ability to handle combined material thicknesses of up to 1/2 inch per step. This allows you to drill through or ream out misaligned holes in structural steel plates, brackets, and flanges with ease. The 5-step design covers the most common small-diameter fastener sizes from 5/16" up to 9/16", making it an essential addition to any fabricator's toolkit. It effectively eliminates the need to carry multiple twist drills or struggle with standard step bits that bottom out too quickly.

Durability and grip are paramount in the field. The Walter Multi-Step Reamer features a secure 3/8" shank with three flats, ensuring positive drive transmission from your power tool to the workpiece. This "no-slip" design is critical when reaming out tough materials like stainless steel or aluminum, where torque resistance can be high. By providing a solution that both enlarges and aligns holes efficiently, this tool significantly speeds up assembly processes and ensures accurate fitment for bolted connections.

Applications

• Enlarging bolt holes in structural steel beams and plates.
• Aligning misaligned holes in stacked metal sheets.
• Drilling clean, precise holes in stainless steel and aluminum.
• Maintenance and repair operations requiring variable hole sizes.
