OVERVIEW

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.

Key Features & Benefits

  • Heavy-Duty Composition: Made with a cobalt blend to withstand high temperatures generated when drilling hard metals.
  • Self-Centering Point: The 135° split point prevents walking and allows for precise starts without pilot holes.
  • Optimized Geometry: Quick-flow spiral design ejects chips efficiently, reducing friction and heat.
  • Versatile Application: Excellent for stainless steel, mild steel, and non-ferrous metals.

FAQ

A #53 wire gauge drill bit has a decimal equivalent diameter of 0.0595 inches.

Yes, the Walter SST+ series is specifically engineered with a cobalt blend to drill through stainless steel and other hard alloys effectively.

No, the 135° split point design is self-centering, which prevents the bit from walking and eliminates the need for a center punch.

The cobalt blend increases the heat resistance and hardness of the bit, allowing it to maintain a sharp edge longer when drilling tough materials that generate high heat.

Yes, the 01B553 is a standard jobber length bit, which is the most common length for general-purpose drilling, offering a good balance of reach and strength.

While the bit is heat-resistant, using a high-quality cutting lubricant (like Walter Coolcut) is highly recommended when drilling stainless steel to extend tool life and improve the finish.

When drilling stainless steel, it is generally best to use a slower RPM and apply consistent pressure to prevent the material from work-hardening.

Yes, the Walter 01B553 has a round shank that fits securely into standard keyed and keyless chucks found on portable hand drills.
