OVERVIEW

The Toughest Little Bit for Your Drill

Every welder knows the frustration of snapping a drill bit halfway through a job, especially when you are trying to drill out a spot weld or put a hole in a stainless steel bracket. The Walter 01H027 27/64" SST Stub Drill is built to solve exactly that problem. By shortening the bit to a "stub" length, Walter has created a tool that is incredibly stiff and resistant to breaking. It doesn't flex or wobble like those long, flimsy bits you find at the hardware store. This means you can lean into the cut and get the hole drilled faster, even in tight spaces where a long bit just won't fit.

Drilling stainless steel is notorious for burning up bits if they don't cut immediately. As soon as a bit rubs instead of cuts, the stainless work-hardens and becomes nearly impossible to drill. The Walter SST Stub Drill uses a specialized 135-degree split point that bites into the metal the instant it touches the surface. You don't need to waste time hunting for a center punch or worrying about the bit skating across your fresh finish. It grabs, cuts, and clears chips efficiently, thanks to the special bronze surface treatment that helps keep the bit cool and slick.

This bit is a lifesaver for auto body work, sheet metal fabrication, and general repairs. Because it is short, it is perfect for drilling out rivets or making holes in thin sheet metal without tearing the material or grabbing violently as it punches through. It gives you more control over your hand drill, resulting in cleaner, rounder holes every time. If you are tired of buying cheap bits that dull after two holes or snap when you look at them wrong, upgrade to the Walter SST Stub Drill. It’s the professional choice for serious metalworkers who value their time and tools.

Why Welders Love It:

  • Fits Anywhere: Short length gets into wheel wells, cabinets, and tight corners.
  • Bites Hard: No walking or skating, even on round tubing.
  • Lasts Longer: Resists snapping and stays sharp in stainless steel.

FAQ

A stub drill (or screw machine length drill) has a shorter flute and overall length than a standard jobber drill. This makes the stub drill much more rigid, reducing the chance of breakage and improving accuracy, especially in portable drilling applications.

Generally, no. The 01H027 features a 135° split point which is self-centering. It is designed to penetrate the material immediately upon contact without 'walking', eliminating the need for a center punch in most applications.

Yes, the Walter SST Stub Drill is specifically engineered for high-tensile materials like stainless steel. The bronze SST surface treatment and heavy-duty web construction help manage the heat and stress associated with drilling stainless.

The special bronze SST surface treatment reduces friction between the bit and the workpiece. This helps to lower drilling temperatures, prevents chip welding, and extends the overall life of the tool.

Yes, it can drill non-ferrous metals like aluminum effectively. However, because it is designed for harder metals, you should ensure you clear chips frequently to prevent clogging the flutes when working with soft, gummy aluminum.

A 135-degree point is flatter, which engages more cutting lip with the material sooner. This reduces the thrust load required to penetrate hard metals and provides better centering stability than the sharper 118-degree point.

Yes, the 01H027 has a round shank that fits standard 3-jaw chucks found on most cordless and corded power drills.

27/64 inches is approximately 10.72 mm.
