01J037 - Walter SST+ #37 Cobalt Stub Drill Bit for Stainless Steel

High-Performance Drilling with Walter SST Stub Drills

The Walter 01J037 #37 SST Stub Drill is engineered for professionals who demand precision and durability in their metalworking tools. Part of Walter's renowned SST+ line, this drill bit features a premium cobalt blend formulation that significantly extends tool life, even when drilling through hardened materials like stainless steel. The 'stub' or screw machine length design is a critical feature, offering a shorter overall length and flute length compared to standard jobber bits. This compact geometry drastically increases the rigidity of the bit, minimizing flexing and virtually eliminating the risk of breakage under heavy feed pressure.

Designed specifically for sheet metal and thin-walled structures, the Walter #37 bit utilizes a 135° split point. This self-centering geometry allows the drill to bite into the material immediately upon contact, preventing the 'walking' or skating effect common with standard bits. This ensures precise hole placement without the need for a center punch. The exclusive bronze SST surface treatment further enhances performance by reducing friction and facilitating smoother chip evacuation, keeping the cutting edge cooler for longer. Whether you are working with mild steel, non-ferrous metals, or tough stainless alloys, this drill bit delivers consistent, round holes with minimal burrs.

Ideal for use in portable hand drills where stability can be a challenge, the added rigidity of the stub design provides the operator with greater control. It is also perfectly suited for stationary setups where space is limited or maximum stiffness is required. Invest in the Walter 01J037 for a drilling solution that combines speed, accuracy, and longevity.
