01B553 - Walter SST+ Jobber Drill Bit, Wire Gauge #53, 135-Degree Split Point

Walter SST+ Jobber Drill Bit #53 – Precision Drilling for Tough Metals

The Walter 01B553 is a high-performance #53 wire gauge jobber drill bit from the renowned SST+ series. Designed by Walter Surface Technologies, this drill bit is engineered to tackle the toughest drilling applications, specifically targeting stainless steel and other hard metal alloys. Unlike standard high-speed steel bits that dull quickly when facing the heat and hardness of stainless steel, the SST+ line incorporates a specialized cobalt blend. This material composition significantly increases the bit's heat resistance and red hardness, allowing it to maintain a sharp cutting edge even under high-stress conditions.

One of the standout features of this #53 drill bit is its 135° split point geometry. This self-centering design is a game-changer for fabricators and maintenance professionals. It eliminates the need for a center punch, as the bit bites into the material immediately upon contact without "walking" or wandering across the surface. This is particularly beneficial when drilling on curved surfaces such as pipes or tubing. The precision-ground flutes are designed with a unique helix angle that promotes rapid chip evacuation. Efficient chip removal is critical in drilling stainless steel to prevent heat buildup, which can cause the material to work-harden and ruin the drill bit.

Whether you are working in an industrial fabrication shop, performing automotive repairs, or managing MRO tasks, the Walter SST+ #53 drill bit delivers consistent, accurate holes with minimal effort. Its robust construction reduces the likelihood of breakage, saving time and money on replacements. Compatible with both stationary drill presses and portable hand drills, this bit is a versatile addition to any tool crib.
