OVERVIEW

High-Performance Tapping for Portable Drills

The Walter SST Power Tap (1"-8 UNC) represents a leap forward in threading technology, specifically engineered to address the challenges of using reversible portable drills. Standard taps often struggle with alignment and chip evacuation when used in handheld power tools, leading to breakage and poor thread quality. Walter Surface Technologies has solved this with the SST Power Tap series, designed to deliver unparalleled speed, precision, and longevity in demanding industrial environments.

Advanced Geometry for Efficiency

At the heart of this tool is the exclusive Power Tip. This unique feature serves a dual purpose: it acts as a pilot to self-align the tap with the hole axis, ensuring straight threads every time, and it helps eject chips ahead of the cutting action. This "spiral point" effect makes the tap ideal for through-holes, as it prevents chip packing that can snap the tool. Operators can tap continuously without the frequent backing-out required by conventional taps.

Built for Tough Materials

Constructed to handle the rigors of modern fabrication, the Walter 03B661 is optimized for working with stainless steel, mild steel, and various non-ferrous metals like aluminum. The tap features a specialized SST surface treatment that significantly reduces friction during the cutting process. This not only lowers the torque required by the drill but also minimizes heat buildup, preventing work-hardening of the material and extending the life of the tap.

Secure Grip and Durability

Slippage in the drill chuck is a common frustration that damages both the tool shank and the chuck jaws. To combat this, Walter has designed the shank with three precision-ground flats. This ensures a positive, non-slip lock within the drill chuck, transmitting maximum torque to the cut. Whether you are repairing damaged threads in the field or fabricating new components in the shop, the Walter SST Power Tap provides the reliability and performance professionals demand.

FAQ

The Power Tip is a specialized geometry at the front of the tap that helps self-align the tool with the hole axis and ejects chips forward, making it easier to start threads with a portable drill.

This tap is designed primarily for through-holes because it ejects chips forward. Using it on blind holes may cause chips to pack at the bottom, potentially breaking the tap.

It is designed for use on steel, stainless steel, aluminum, and other non-ferrous metals.

Yes, while the SST surface treatment reduces friction, using a high-quality cutting lubricant like Walter Coolcut is always recommended to extend tool life and improve thread quality.

The 3 flats are designed to fit securely into the jaws of a drill chuck, preventing the tap from spinning or slipping during high-torque operations.

No, this tap is designed for reversible portable drills with a standard chuck. Impact drivers may apply excessive shock load that could shatter the tap.

This specific tap (SKU 03B661) cuts a 1"-8 UNC thread.

The SST surface treatment provides a lubricious layer that reduces friction and heat buildup, which is critical when tapping tough materials like stainless steel.
