01W111 - Walter Titanium Coated Step Drill 1/4-3/4 Inch

Precision Multi-Step Drilling for Sheet Metal

The Walter 01W111 Multi-Step Drill Bit is an expertly engineered cutting tool designed to bring versatility and precision to metal fabrication tasks. Capable of drilling holes ranging from 1/4 inch to 3/4 inch, this single bit eliminates the need to constantly change tools when working with varying hole diameters. It is specifically optimized for use on sheet metal, stainless steel, and other thin-walled materials up to 1/8 inch thick. The step design allows operators to drill new holes or enlarge existing ones with exceptional control and accuracy.

Advanced Titanium Coating

Durability is a key feature of the 01W111. The bit features a specialized titanium coating that provides superior resistance to heat and wear. This coating is particularly beneficial when drilling harder materials like stainless steel, where friction heat can rapidly degrade standard high-speed steel bits. By maintaining a harder cutting edge and reducing friction, the titanium coating ensures the bit stays sharp longer, providing a better return on investment for professional users.

Chatter-Free Performance

Drilling thin sheet metal often results in vibration, chatter, and irregular hole shapes. Walter has addressed this with a two-wide-flute design that stabilizes the drilling process. These deep flutes efficiently evacuate chips, preventing buildup that can cause overheating or binding. Furthermore, the bit is equipped with a self-centering point that bites into the material immediately upon contact. This feature removes the need for pre-drilling pilot holes or using a center punch, streamlining the workflow and ensuring precise hole placement every time.

Applications and Utility

This multi-step drill is an essential tool for electricians, HVAC technicians, and metal fabricators who frequently work with electrical panels, ductwork, and automotive body panels. Its ability to produce clean, burr-free holes in a single pass makes it a time-saving solution for installation and repair work. Whether enlarging a conduit knockout or fabricating a custom bracket, the Walter 01W111 delivers consistent, professional results.
