Core Advantages & Detailed Product Features

1. Premium Industrial-Grade Tungsten Carbide Cutting Teeth, Ultra-Wear Resistant & Long Service Life

• Each cutting tooth is made of high-grade YG8 tungsten carbide, with a hardness up to HRA 92.5+, featuring super strong wear resistance, impact resistance and excellent high-temperature red hardness. It maintains sharp cutting edges even under continuous high-temperature cutting on high-hardness materials, with a service life 5-8 times longer than ordinary bi-metal hole saws and 10 times longer than HSS hole saws.
• The carbide teeth are welded by high-frequency silver brazing technology, with high welding strength, no tooth loss, no chipping even under heavy-load impact cutting, perfectly adapting to harsh cutting environments of stainless steel and thick steel plates.
• The optimized tooth tip angle design is specially developed for metal cutting, with sharp cutting, minimal burrs, and smooth hole wall finish, eliminating the need for secondary reaming and finishing operations.

2. High-Strength Hardened Alloy Steel Body, Anti-Deformation & Anti-Torsion

• The main body of the hole saw is manufactured from high-grade 40Cr chromium-molybdenum alloy steel, with overall quenching and tempering treatment, reaching a hardness of HRC 40-45. It has super high torsional strength, anti-deformation and anti-vibration performance, no cracking, no bending even under high-load continuous cutting, ensuring stable cutting performance.
• The body surface is treated with blackening anti-rust treatment, which has excellent corrosion and rust resistance, adapting to humid and harsh construction environments, and extending the service life of the product.
• The precision machined body with strict concentricity control ensures perfect roundness of the cut hole, no elliptical hole, no deviation, meeting the high-precision machining requirements of industrial scenarios.

3. Precision Centering Pilot Drill & Spring Design, Accurate Positioning & Smooth Operation

• Equipped with a high-precision HSS center pilot drill, which can quickly and accurately locate the drilling position, no slipping, no wandering during the cutting process, even on curved surfaces, inclined surfaces and irregular workpieces, ensuring accurate hole positioning and stable cutting.
• The built-in high-strength spring has an optimized elastic design, which can automatically eject the internal material core after the hole cutting is completed, no stuck core, greatly improving work efficiency, and providing stable buffer during the cutting process to avoid sudden impact and tooth chipping.
• The side of the body is designed with a chip removal hole, which can quickly discharge the cutting chips during the cutting process, avoid chip clogging, reduce cutting heat buildup, and ensure smooth and continuous cutting.

4. Universal Hex Shank Design, Wide Equipment Compatibility

• Adopts industry-standard anti-slip hex shank, available in 10mm and 13mm sizes, which is universally compatible with more than 99% of rotary drilling equipment on the market, including corded/cordless hand electric drills, bench drills, magnetic drill presses, impact drills, milling machines and pneumatic drills.
• The hex shank is precision ground, with strict dimensional tolerance, which can be firmly clamped in the drill chuck, no slipping, no runout during high-speed rotation, ensuring stable power transmission and safe operation.
• The shank and the hole saw body are connected by high-strength set screws, which is firm and reliable, easy to disassemble and replace the pilot drill and the hole saw body, convenient for maintenance and replacement of wearing parts.

5. Optimized Tooth Geometry Design, High-Efficiency Cutting & Low Resistance

• The cutting teeth adopt an optimized staggered tooth design, with a 12° positive rake angle, which reduces cutting resistance by 40% compared with ordinary hole saws, requires less feed force, reduces operator fatigue, and greatly improves cutting efficiency.
• The equal-spacing tooth distribution design ensures even force during the cutting process, low vibration, low noise, and stable cutting, avoiding tool jitter and hole edge damage.
• The tooth tip is precision ground, with a smooth cutting edge, which can cut through various materials smoothly, no tearing, no burrs, and the cut hole has a clean and smooth edge, ready for direct installation of pipes, switches and other components.

Safety Operation Tips

1. Please select the appropriate hole saw diameter according to your actual hole cutting requirements, and ensure the pilot drill and spring are correctly installed before operation.
2. Please wear professional protective equipment during operation, including safety goggles, work gloves and anti-slip safety shoes, to avoid injury from flying chips and splashing cutting fluid.
3. Please control the reasonable rotation speed and feed speed according to the workpiece material: low speed and slow feed for high-hardness materials like stainless steel, to avoid overheating, tooth chipping and drill bit breakage.
4. It is highly recommended to use professional metal cutting fluid during the cutting process, which can effectively reduce the cutting temperature, extend the service life of the hole saw, and improve the hole cutting quality.
5. Please ensure the hole saw is firmly clamped in the drill chuck before operation, and keep the hole saw perpendicular to the workpiece surface during cutting, to avoid deflection and tool damage.
