OVERVIEW

Precision Engineering for Demanding Drilling Applications

The Walter 3/8" SST Stub Drill Bit (SKU: 01H024) represents the pinnacle of drilling efficiency for industrial professionals who demand reliability and precision. Designed specifically for heavy-duty applications, this drill bit features a "stub" or screw machine length. This abbreviated profile is not merely for fitting into confined spaces; it fundamentally alters the mechanics of the drilling operation. By reducing the overall length and flute length, the bit achieves significantly higher rigidity compared to standard jobber bits. This increased stiffness minimizes deflection and vibration, which are the primary causes of bit breakage and inaccurate holes, particularly when working with hard materials like stainless steel or when using hand-held power tools.

At the tip, the Walter SST Stub Drill utilizes a sophisticated 135° split point geometry. Unlike standard 118° points that require a center punch to prevent wandering, this split point bites into the material immediately upon contact. This self-centering capability is crucial for productivity, allowing operators to drill multiple holes rapidly without preparatory steps. It also ensures clean, burr-free entry, which is essential when drilling through thin-walled materials or sheet metal where distortion is a common concern.

Performance is further enhanced by Walter's proprietary bronze SST surface treatment. This specialized coating serves a dual purpose: it increases the surface hardness of the bit and provides a lubricious layer that reduces friction. Lower friction means less heat generation during the cutting process, which preserves the temper of the cutting edge and extends the tool's life. Whether you are drilling mild steel, non-ferrous metals, or challenging stainless steel alloys, the 01H024 delivers consistent, high-quality results. It is an indispensable tool for maintenance, repair, and operations (MRO) environments where efficiency and tool longevity are paramount.

Key Technical Benefits

  • Enhanced Rigidity: Short flute length prevents flexing and snapping under load.
  • Precision Starting: 135-degree split point eliminates walking and the need for center punching.
  • Thermal Management: Bronze SST coating dissipates heat and reduces friction for longer life.
  • Versatile Application: Excellent for both stationary machines and portable hand drills.

FAQ

Stub drills have a shorter flute and overall length, which makes them significantly more rigid. This rigidity reduces deflection and breakage, making them ideal for portable drilling, hard materials, and starting holes accurately.

No, the Walter 01H024 features a 135° split point geometry that is self-centering. It bites into the material immediately, preventing the bit from 'walking' across the surface.

Yes, the SST (Super Speed Tip) design and bronze surface treatment are specifically engineered to handle tough materials like stainless steel effectively by reducing heat and friction.

The bronze SST coating provides a heat-resistant and lubricious surface. This helps evacuate chips more efficiently and keeps the cutting edge cooler, extending the life of the drill bit.

Absolutely. The short length prevents flexing, and the split point ensures a clean entry, making it excellent for thin-walled materials and sheet metal where precision is required.

This is a 3/8" diameter bit with a round shank, so you will need a drill with a chuck capacity of at least 3/8" (10mm) or larger.

It is called a stub drill because it is manufactured to screw machine lengths, which are shorter than standard jobber lengths. This makes it 'stubby' but also much stronger.

Yes, stub drills are actually preferred for hand drills because they are less likely to snap if you accidentally tilt the drill while working.
