OVERVIEW

High-Performance Rigidity for Industrial Drilling

The Walter 01J038 #38 SST Stub Drill Bit is engineered for professionals who demand precision and durability in their metalworking tools. Part of Walter's renowned SST+ line, this drill bit is specifically designed to tackle the challenges of drilling through sheet metal and tough alloys. The "stub" or screw machine length provides exceptional rigidity compared to standard jobber length bits. This reduced length significantly lowers the risk of deflection and breakage, making it the ideal choice for high-torque applications or when working with hand-held drills where stability can be compromised.

Manufactured from a specialized cobalt blend, this bit offers superior heat resistance and hardness, allowing it to maintain a sharp cutting edge even when drilling through abrasive materials like stainless steel. The addition of a unique bronze SST surface treatment further enhances performance by reducing friction and facilitating smoother chip evacuation. This results in cleaner holes and a longer tool lifespan, reducing the frequency of replacements in high-volume production environments.

One of the standout features of the 01J038 is its split point geometry. This design ensures the bit begins cutting immediately upon contact with the material, eliminating the need for a center punch and preventing the bit from "walking" across the surface. This is particularly beneficial when drilling into rounded surfaces or polished sheet metal. Whether used in a stationary drill press or a portable drill, the Walter #38 SST Stub Drill delivers consistent, reliable performance for MRO and fabrication tasks.

Key Technical Benefits

  • Enhanced Durability: Cobalt blend construction withstands high temperatures generated during drilling of hard metals.
  • Maximum Rigidity: Short flute design prevents flexing and snapping, ensuring straight, accurate holes.
  • Efficiency: Split point tip allows for faster penetration rates and reduces operator fatigue.

FAQ

A #38 wire gauge drill bit has a diameter of 0.1015 inches.

Stub drills have shorter flutes and a shorter overall length, making them much more rigid. This rigidity prevents flexing and breakage, especially when drilling hard materials or using hand drills.

Yes, the Walter SST drill bits are made with a cobalt blend specifically designed to withstand the heat and hardness of drilling stainless steel.

The split point design allows the bit to self-center immediately upon contact, preventing it from 'walking' or skating across the surface of the metal.

Yes, the bronze surface treatment reduces friction between the bit and the workpiece, which helps lower heat buildup and improves chip flow.

Absolutely. While it is tough enough for stainless steel, it is also excellent for non-ferrous metals like aluminum and copper.

SST refers to Walter's 'Super Speed Tip' or surface treatment technology designed to enhance drilling speed and tool life.

Yes, this SKU represents a single drill bit, though they are often used in bulk for production environments.
