01H123 - Walter 23/64" SST+ Stub Drill Bit with Hex Shank

High-Performance Drilling for Tough Materials

The Walter 23/64" Hex SST Stub Drill (SKU: 01H123) is engineered for industrial professionals who demand precision and durability. Designed with a heavy-duty stub length geometry—often referred to as screw machine length—this bit offers significantly higher rigidity compared to standard jobber drills. This increased stiffness reduces deflection and vibration, minimizing the risk of breakage even under heavy feed pressure.

At the tip, the drill features a sophisticated 135° split point. This geometry is self-centering, allowing the operator to start holes accurately on flat or curved surfaces without the need for a center punch or pilot hole. It effectively prevents "walking," ensuring precise hole placement every time. The specialized Bronze SST surface treatment is a key differentiator, providing a heat-resistant shield that reduces friction and facilitates chip evacuation. This treatment is particularly effective when drilling high-tensile materials like stainless steel, where heat buildup is a primary cause of tool failure.

The inclusion of a hex shank transforms the utility of this tool, ensuring a positive lock in drill chucks to eliminate slippage under high torque. It also makes the bit compatible with quick-change impact drivers, adding versatility to your toolkit. Whether working on thin-walled sheet metal or solid structural components, the Walter SST Stub Drill delivers clean, burr-free holes with exceptional efficiency.
