Our sintered multi-layer segmented hole saws (heavy-duty hole cutting tools featuring custom CNC-machined steel barrels, multi-layer sintered diamond segments, and integrated pilot centering bits) are engineered specifically for high-efficiency, fast, and smooth core drilling through tough, thick, and abrasive materials. Constructed by metallurgical sintering of high-density matrix segments onto precision-turned alloy steel bodies, these hole saws deliver extraordinary cutting endurance, fast chip removal, and superior dimensional stability.
They are extensively utilized across stone processing, building construction, electrical installation, and industrial hardware metalworking:
Heavy Stone & Masonry Cutting: Ideal for rapid hole drilling through granite countertops, marble slabs, quartz surfaces, hard bricks, and concrete structures.
Thick Metal & Stainless Steel Panels: Perfect for cutting clean cable pass-throughs, pipe openings, and junction knockouts in thick stainless steel, sheet metal, and aluminum junction boxes.
Tile, Porcelain & Architectural Panels: Applied for precise, chip-free hole cutting in thick vitreous porcelain tiles, ceramic wall panels, and optical composites.
Fiberglass & Industrial Composites: Used for drilling burr-free openings in heavy FRP structures, carbon fiber panels, and hard synthetic plastics.
Sintered Multi-Layer Segment Technology: Multi-layer sintered matrix continuously exposes sharp diamond/alloy grains as it wears, delivering outstanding cutting speed and multiple times the service life of standard coated hole saws.
Precision CNC Machined Steel Barrel & Shank: Barrel bodies and drive shanks are turned and bored on multi-axis CNC machining centers to ensure tight concentricity (+/-0.005 mm), zero wobble, and smooth power transmission.
Pilot Drill Bit & Ejector Spring Assembly: Features a precision center pilot drill bit for accurate hole positioning without slipping, combined with a heavy-duty spring that automatically ejects the cut core after drilling.
Optimized Swarf Evacuation Flutes: Deep side slots and wide tooth gullets efficiently flush out swarf and debris, preventing binder clogging, reduce friction heat, and prolong tool longevity.
Versatile Shank & Size Options: Fully customizable in hole diameters (16 mm to 100+ mm), arbor adapter styles (triangle shank, hex shank, SDS-plus), depth of cut, and laser-etched custom logos.
Backed by over 10 years of intensive CNC machining experience, we are an all-around custom hardware manufacturing facility dedicated to delivering ultra-precision component processing services.
