OVERVIEW

Heavy-Duty Drilling Performance in Compact Spaces

The Walter 9/32" Hex SST Stub Drill (01H118) is engineered for professionals who demand precision, durability, and versatility in their drilling operations. Known as a "stub" or screw machine length drill, this tool features a shorter flute and overall length compared to standard jobber bits. This compact design significantly increases the rigidity of the bit, making it highly resistant to breakage even under heavy feed pressure. It is the ideal solution for drilling into thin-walled materials like sheet metal, where long bits often flex or wander.

Advanced Geometry for Stainless and Steel

Drilling into tough materials like stainless steel requires a bit that can bite immediately without skating. The Walter SST Stub Drill is equipped with a 135° split point. This self-centering geometry eliminates the need for pre-drilling or center punching, allowing you to start holes precisely where you need them. The split point design also reduces the thrust force required to penetrate the material, resulting in less operator fatigue and faster cycle times.

Quick-Change Hex Shank

Efficiency on the job site is critical, and the integrated Hex shank on this drill bit is a game-changer. Unlike round shanks that can slip inside a drill chuck under high torque, the hex design locks positively into place, ensuring maximum power transfer. It also makes this bit compatible with quick-change adapters and impact drivers, allowing for rapid swapping between drilling and driving tasks without needing to manipulate a chuck key.

SST Surface Treatment

To further enhance performance, Walter applies a special bronze SST surface treatment to these bits. This coating helps to dissipate heat and reduce friction during the drilling process, which is essential when working with work-hardening materials like stainless steel. The result is a drill bit that stays sharper longer, produces cleaner holes with fewer burrs, and delivers a lower cost per hole over its lifespan.

FAQ

Stub drills are shorter, which makes them much more rigid and less prone to breaking. This rigidity allows for more precise drilling, especially in sheet metal, and fits better in tight spaces.

No, this drill bit features a 135° split point which is self-centering. It bites into the material immediately upon contact, eliminating the need for center punching.

Yes, the hex shank design allows this drill bit to be used in quick-change impact drivers as well as standard drill chucks.

Yes, the Walter SST Stub Drill is designed with a special bronze surface treatment and heavy-duty geometry specifically for drilling stainless steel and other tough alloys.

It is suitable for mild steel, stainless steel, non-ferrous metals (like aluminum), and sheet metal.

The bronze SST (Super Speed Tip) surface treatment reduces friction and helps dissipate heat, which extends the life of the drill bit and improves cutting efficiency.

The Walter 01H118 has a diameter of 9/32 inches.
