Bosch Hole Saw HDG112 1-1/2 Inch Diamond Grit Vacuum Brazed Wet Core Cutter (Quick Change Mandrel Porcelain Granite Glass Ceramic Tile Plumbing Boring Tool)

Contractor-Grade 1-1/2-Inch Vacuum-Brazed Diamond Core Saw with Segmented Heat-Dissipation Teeth and Quick-Change Mandrel Integration

The Bosch HDG112 1-1/2 Inch Diamond Grit Hole Saw Vacuum Brazed for Porcelain Granite Glass and Tile Wet Cutting delivers specialized structural masonry excavation utility and exceptional hard-substrate coring efficiency across demanding residential bathroom renovations, stone countertop installations, and commercial tile staging configurations. Engineered with premium vacuum-brazed diamond grit bound natively to a reinforced cylindrical alloy chassis, this high-performance layout tool cleanly penetrates the most resilient mineral surfaces while entirely avoiding edge cracking or glaze fractures. This professional contractor solution resolves rapid thermal bit degradation, core plug friction binding stalls, and messy layout wandering by combining a specialized wet-cutting segmented tooth geometry with high-clearance side slot ejection ports and native Quick Change universal mandrel compatibility. Outfitted with an essential 1-1/2 inch cutting diameter, a matching 1-1/2 inch operational depth capacity, a 2.9375-inch total structural reach, and strict requirements for water-cooled runtime loops, this robust coring cutter optimizes subcontractor jobsite speed variables during plumbing pipe pass-through routing, shower hardware mounting, and structural stone adjustments.

Best Used For:

• Porcelain and Ceramic Core Boring: Drilling clean, chip-free 1-1/2 inch pathways natively through high-PEI ceramic shower tiles and vitreous porcelain backing walls without material structural failure.
• Granite Countertop Plumb Rough-Ins: Establishing smooth utility routing entry openings inside thick granite, quartz, and slate solid surface slabs single-handedly for fixture valve assemblies.
• Glass Sheet Panel Perforations: Slicing crisp architectural openings cleanly through thick structural glass sheets under wet irrigation streams to route hardware mount anchorages safely.

Key Performance & Safety Features

• Vacuum-Brazed Diamond Coating: Micrograin industrial diamond matrix isolates extreme abrasive friction wear loops completely, extending active tool lifespan parameters over standard carbide variations.
• Segmented Tooth Engineering: Advanced cooling gaps engineered into the cutting face accelerate dynamic slurry evacuation velocities and lower localized material expansion stress drops.
• Tool-Free Quick Change Sync: Specialized shoulder mounting geometry locks natively inside universal quick-change arbors, maximizing overall jobsite tooling swap throughput.
• Side Plug Core Ejection: Structural side-wall window ports drop internal stone binding risks significantly, accelerating core disk removal cycles between sequential operations.
• Wet Sawing Thermal Defense: Fluid-cooled runtime parameters suppress hazardous crystalline airborne dust vectors while preserving diamond edge configuration integrity under load.

What's Included

• (1) Bosch 1-1/2 Inch Vacuum-Brazed Diamond Grit Hole Saw Cup (HDG112)
• Note: Drive arbor mandrel assembly and pilot drill centers are sold separately.

Technical Specifications

Pro-Tip: When commencing a wet stone core penetration, lean the saw at a shallow 45-degree approach vector to allow the diamond matrix edge to establish a crescent layout groove. Once this track is bit stabilized, smoothly articulate the tool upright to full axial alignment while keeping a uniform irrigation stream across the segment walls.
