The Problem: Boring multiple 25mm holes in industrial control panels (often 304/316 Stainless) creates localized heat spikes. Standard High-Speed Steel (HSS) bits can suffer "thermal rounding," where the teeth soften and fail to penetrate after only a few cycles.
The Result: Project delays, increased overhead for replacement bits, and jagged hole edges that prevent a proper IP68-rated waterproof seal for electrical glands.
Work Hardening: 25mm is a mid-range diameter that generates enough speed to cause "work-hardening" on stainless steel surfaces if the feed pressure is inconsistent.
Inadequate Chip Clearing: At this diameter, metal shavings often clog the cutting path, acting as an abrasive that blunts the tool from the side.
YG10 Industrial Carbide: Unlike standard YG8, our 25mm series utilizes YG10 Grade Tungsten Carbide. This grade offers a superior balance of hardness (HRA 91) and impact toughness, making it more resistant to chipping during the breakthrough phase of the cut.
Triple-Stage Cutting Path: The teeth are precision-ground into three distinct cutting zones: Outer, Middle, and Inner. This divides the material removal into smaller chips, reducing the required torque and preventing the tool from "grabbing" the material.
M25 Optimized Centering: The integrated 6mm pilot drill is specifically calibrated to stabilize the 25mm cup for standard M25 junction box entries. This ensuring a "perfect-fit" clearance every time.
| Technical Pillar | Specification Detail | Industrial Benefit |
| Diameter | 25mm (approx. 1-inch) | Standard fit for M25 electrical glands. |
| Effective Depth | 25mm (1-inch) | One-pass boring through industrial plate. |
| Tip Material | YG10 Tungsten Carbide | Superior edge life in 316 Stainless Steel. |
| Shank Type | 10mm Triangular Shank | Zero-slip mechanical lock in 3-jaw chucks. |
| Whole Length | 90mm | High-rigidity design for industrial drill presses. |
| Concentricity | TIR <= 0.10mm | Precision finish, no deburring required. |
Industrial Electrical MEP: The primary size for installing M25 cable glands, push-buttons, and pilot lights in stainless steel and alloy enclosures.
Fluid Management MRO: Precision boring for 1-inch fluid transport lines and manifold entries in aluminum or cast iron housings.
Automotive and Marine MRO: Ideal for creating clean entries in thick-walled bulkheads and alloy frames where tool longevity is critical.
Material Versatility: Optimized for Stainless Steel (10mm or less), Iron Plate (25mm or less), Aluminum, and Thick-Walled Plastics.
RPM Strategy: For 25mm in stainless steel, maintain 400 - 550 RPM. For mild steel, maintain 550 - 750 RPM.
Ejection Logic: The high-tension internal spring is designed to eject the 25mm metal slug instantly, preventing the slug from welding to the interior of the carbide cup under heat.
Q: Why use 25mm instead of a 1-inch (25.4mm) saw for electrical work?
A: In the international B2B sector, M25 is the metric standard. A true 25mm saw provides a much snugger, more professional fit for M25 cable glands. This ensures that the rubber gasket of the gland creates a total waterproof seal against the enclosure wall.
Q: Can this saw handle "interrupted cuts" on textured surfaces?
A: Yes. The YG10 carbide grade is chosen for its superior shock resistance. This allows the 25mm cup to maintain its integrity even when boring into checkered plates or surfaces with inconsistent density.
Q: Does the pilot drill require a different speed?
A: No. The pilot bit is designed to lead the 25mm carbide teeth. Simply ensure the pilot has fully penetrated the surface before applying full pressure to engage the carbide teeth. This prevents "tip-shock" and extends the life of the tool.
