OVERVIEW

High-Performance Drilling with Walter SST+ Technology

The Walter 01R227 SST+ Drill Bit is a premium cutting tool engineered for industrial professionals who demand precision and durability. With a diameter of 27/64 inches, this bit features a specially designed 3/8-inch reduced shank, making it compatible with a wider range of power tools, including those with limited chuck capacity. This design innovation allows operators to drill larger holes without upgrading to heavier, bulkier drilling equipment.

Manufactured with Walter's proprietary SST+ geometry, this drill bit is optimized for working with tough materials such as stainless steel, mild steel, and non-ferrous metals. The core material is a high-grade High-Speed Steel (HSS) formulation that withstands high temperatures and torque, significantly extending the tool's lifespan compared to standard black oxide bits. The precision-ground flutes ensure rapid chip evacuation, reducing heat buildup and preventing work-hardening of the material.

A key feature of the 01R227 is its 135° self-centering split point. This tip geometry bites into the metal immediately upon contact, eliminating the "walking" or skating often experienced with standard 118° bits. This precision makes it ideal for drilling on curved surfaces or round stock without the need for a center punch pilot hole. Whether used in a stationary drill press or a portable hand drill, the Walter SST+ series delivers consistent, round, and burr-free holes in the most demanding industrial environments.

FAQ

This drill bit features a 3/8" reduced shank, allowing it to fit into standard 3/8" drill chucks despite the bit diameter being larger.

Yes, the SST+ series is specifically engineered with a heavy-duty geometry and material blend ideal for drilling stainless steel and other hard alloys.

Generally, no. The 135° self-centering split point prevents the bit from walking, allowing you to start drilling directly on the mark.

This bit creates a hole with a diameter of 27/64 inches.

Absolutely. The reduced shank is designed specifically to allow portable drills (which often have 3/8" chucks) to drive this larger bit.

It is made from high-performance High-Speed Steel (HSS) with Walter's SST+ geometry for extended life.

Yes, it is effective on non-ferrous metals like aluminum, as well as mild and stainless steel.
