OVERVIEW

Heavy-Duty Precision for Confined Spaces

The Walter 15/64" SST+ Stub Drill Bit (SKU: 01H115) is engineered for industrial professionals who demand precision, durability, and efficiency. Known as a "stub" or screw machine drill, this bit features a shorter flute and overall length compared to standard jobber bits. This compact design significantly increases the rigidity of the bit, minimizing deflection and virtually eliminating the risk of breakage under torque. It is the ideal choice for drilling into sheet metal, thin-walled tubing, and other materials where stability is paramount.

One of the standout features of the SST+ series is the 135° split point geometry. Unlike standard 118° points, this self-centering design bites into the material immediately upon contact, preventing the bit from "walking" or skating across the surface. This eliminates the need for pre-drilling or center punching, saving valuable time during fabrication. The bit is particularly effective on curved surfaces, such as pipes or rounded automotive panels, where maintaining accuracy can be challenging.

Constructed from premium High-Speed Steel (HSS) and finished with a special bronze SST surface treatment, this drill bit is built to withstand high temperatures and friction. The bronze coating acts as a lubricant and heat shield, extending the tool's life even when drilling through tough alloys like stainless steel. Whether you are working in a machine shop or on a field repair, the Walter 01H115 delivers consistent, burr-free holes with exceptional speed.

Key Technical Benefits

  • Maximum Rigidity: Short flute length reduces flex, ensuring straight, accurate holes.
  • Self-Centering: 135° split point engages instantly without wandering.
  • Heat Resistant: Bronze surface treatment promotes chip flow and reduces heat buildup.

FAQ

Stub drill bits have a shorter flute and overall length, which makes them much more rigid than standard jobber bits. This rigidity prevents flexing and breakage, making them ideal for drilling hard materials or for use in portable drills where stability is key.

No, the Walter 01H115 features a 135° split point that is self-centering. It is designed to penetrate the material immediately upon contact without walking, eliminating the need for center punching.

Yes, the SST+ line is specifically formulated with a heavy-duty HSS construction and bronze surface treatment to effectively drill through tough materials like stainless steel.

The decimal equivalent of a 15/64" drill bit is approximately 0.2344 inches.

Absolutely. The short length makes it very stable and easy to control, which is perfect for hand-held drilling operations where long bits might wobble or break.

The special bronze SST surface treatment helps to reduce friction and dissipate heat during drilling. This prevents the bit from overheating and extends its cutting life.

While the product name may sometimes include 'Hex' in loose terminology, the 01H series are typically round shank stub drills designed for standard chucks. Please verify your specific chuck requirements.
