The Problem: Boring 25mm (1-inch) holes in industrial grade steel often results in "oval" holes or "chatter marks" when using standard bits. Furthermore, when cutting through 304 stainless steel or hardened alloys, the heat generated at this diameter causes standard steel teeth to blunt almost instantly.
The Result: Poor fitment for 25mm electrical glands or sensors, and a high rate of tool replacement, which increases the operational cost per hole.
Torque Load: At 25mm, the tool encounters significant resistance. If the body of the saw is not perfectly concentric, it creates rhythmic vibration that prevents a clean cut.
Thermal Clogging: Without specialized gullets, the metal shavings (chips) become trapped in the cutting path. This causes "re-cutting" of chips, which generates extreme heat and leads to the thermal failure of the tool's edge.
M2 Grade Red-Hardness: Our 25mm Industrial Series is forged from HSS M2 (W6Mo5Cr4V2). This molybdenum-based steel provides exceptional "red-hardness," maintaining a razor-sharp 64-66 HRC edge even when temperatures at the cutting tip exceed 600°C.
Integrated Monoblock Design: By utilizing a one-piece ground construction, we eliminate the stacking tolerances found in arbor-mounted saws. This ensures a Total Indicator Runout (TIR) ≤ 0.10mm, providing the stability needed for machine-perfect circularity.
Advanced Chip-Breaker Geometry: Each tooth is precision-ground with a triple-edge profile. This design breaks the metal waste into small, manageable chips that are instantly cleared by the deep-gullet system, preventing heat-soak and binding.
| Technical Pillar | Specification Detail | Industrial Benefit |
| Material Grade | HSS M2 (Industrial Grade) | Durability: 3x longer life than 4341 steel. |
| Boring Accuracy | TIR (Runout) ≤ 0.10mm | Stability: Eliminates vibration and "walking." |
| Total Length | 70mm - 75mm | Versatility: Compatible with all standard drills. |
| Cutting Depth | ≤ 5mm (Industrial Plate) | Efficiency: Perfect for sheet metal and profiles. |
| Hardness (HRC) | 64 - 66 HRC | Edge Retention: Sharpness through 304 Stainless. |
| Safety Feature | Safety Stopper Flange | Control: Prevents plunging into interior wiring. |
Industrial Electrical Systems: The gold standard for boring precision entries for 25mm cable glands, conduits, and safety switches in metal cabinets.
Mechanical & Fluid MRO: Ideal for installing 25mm sensors and pipe fittings in aluminum profiles, copper manifolds, and thin-walled alloy tanks.
Automotive Fabrication: Precision boring in vehicle chassis components and body panels where clean, burr-free finishes are required for accessory mounting.
Material Versatility: Optimized for Stainless Steel (≤ 2.5mm), Alloy Steel, Aluminum, Brass, and Copper.
Speed Management: For 25mm in mild steel, maintain 350 - 450 RPM. For 304 Stainless Steel, reduce to 180 - 220 RPM to ensure maximum tool life.
Lubrication Protocol: To maintain the structural integrity of the M2 teeth, always use a high-quality cutting oil or paste. This facilitates chip evacuation and reduces friction-induced wear.
Q: Why choose a 25mm HSS saw instead of a 25mm step drill?
A: A hole saw is much more efficient for consistent 25mm bores. It removes less material (only the perimeter), which requires less torque from your drill and generates significantly less heat, leading to a much longer tool life in thick metals.
Q: Is the pilot drill replaceable?
A: Yes. The 135° split-point center drill is secured by a side-mounted grub screw. If the pilot becomes dull, it can be easily replaced using the provided hex key to ensure the tool continues to center perfectly.
Q: Can this be used with a magnetic drill press?
A: Absolutely. The integrated hex shank is designed for maximum compatibility, providing a zero-slip connection that is ideal for the high-torque environment of a magnetic or stationary drill press.
Vacuum Heat Treatment: Our M2 steel undergoes a multi-stage vacuum-hardening process to ensure a uniform molecular structure and zero internal stress.
Precision Grinding: Every saw is fully ground from solid stock to ensure perfectly symmetrical teeth and superior concentricity.
Industrial Compliance: Manufactured to meet international engineering tolerances for consistent, safe, and professional boring results.
