01U950 - Walter VP High-Speed Steel Countersink Set - 82 Degree

Precision Countersinking with M2 HSS Durability

The Walter 01U950 Counter Sink Set VP is an essential tooling solution for industrial machinists and fabricators requiring precision hole preparation. Engineered from premium M2 High-Speed Steel (HSS), these countersinks are designed to withstand the high thermal stresses and abrasion associated with cutting tough metals. Unlike standard carbon steel bits, the M2 HSS composition ensures the cutting edges retain their hardness at higher temperatures, significantly extending the service life of the tool when working with stainless steel and other hard alloys.

Each bit in this set features a precision-ground 82-degree point angle, the industry standard for flat-head screws and fasteners. This geometry is meticulously crafted to ensure a perfect flush fit, reducing the likelihood of stress risers around the fastener head. Beyond simple countersinking, these tools excel at deburring drilled holes and chamfering edges to remove sharp burrs, enhancing both the safety and aesthetic quality of the workpiece. The flute design is optimized to evacuate chips efficiently, promoting a smooth, chatter-free finish that requires minimal secondary processing.

Versatility is a core strength of the Walter VP set. It is fully compatible with both portable hand drills and stationary drill presses, making it equally effective for on-site maintenance repairs and production floor manufacturing. Whether you are working with mild steel, stainless steel, or non-ferrous metals like aluminum and brass, this set delivers consistent, high-quality results. Investing in the Walter 01U950 means investing in tooling that reduces downtime and improves the mechanical integrity of your fastened assemblies.
