Bosch Hole Saw HMD137 1-3/8 Inch Daredevil Carbide Multi Material Deep Cut Cup 2-3/8 Depth Wood Tile Brick Block Aluminum Drilling Conduit Boring Tool

EDGE Daredevil 1-3/8-Inch Multi-Material Deep Cut Carbide Hole Saw with 2-3/8-Inch Boring Depth and Specialized Masonry Metal Geometry

The Bosch Daredevil 1-3/8 Inch Carbide Hole Saw Multi Material Deep Cut 10x Faster for Wood Brick and Tile delivers specialized deep-cavity substrate excavation utility and exceptional rapid coring efficiency across demanding commercial plumbing layouts, residential electrical rough-ins, and masonry wall alterations. Engineered with a premium carbide-tipped tooth layout bound natively to a reinforced deep-draw steel cylinder chassis, this high-performance layout tool cleanly penetrates highly abrasive surfaces up to 10x faster than standard bi-metal configurations. This professional contractor solution resolves frequent tool change downtime bottlenecks when hitting embedded brick boundaries, multi-step chip-out fatigue on double-stud frames, and core plug friction lock by combining an extended 2-3/8 inch deep cutting barrel structure with integrated large debris ejection ports and standard threaded arbor mandrel compatibility. Outfitted with an essential 1-3/8 inch cutting diameter path, a 50% deeper cup profile capacity to complete single-pass structural drill cycles, and a hardened tool geometry optimized for structural timber, concrete block, ceramic tile, and aluminum sheets, this robust multi-material boring hardware optimizes subcontractor project metrics during utility conduit routing, switchboard pipe staging, and structural partition modifications.

Best Used For:

• Double-Stud Timber Framing: Boring clean, uniform 1-3/8 inch utility pathways natively through stacked structural double-stud frames and thick joists in a single continuous pass.
• Mixed Masonry Core Drilling: Penetrating commercial brick facings, tough concrete blocks, and internal plaster backings single-handedly without swapping accessories or dulling cutting borders.
• Metal and Tile Perforations: Slicing crisp architectural openings cleanly through structural aluminum panels and dense ceramic tile layers to install mechanical lines or fixture plumbing.

Key Performance & Safety Features

• Premium Hardened Carbide Teeth: Heavy-duty industrial-grade carbide tips isolate extreme friction wear loops completely, easily surviving abrasive masonry contacts that destroy bi-metal units.
• Extended Deep Cup Capacity: Specialized 2-3/8 inch deep structural barrel layout eliminates the standard need to drill, manually chip out the core disk, and re-drill multi-layer walls.
• 10x Accelerated Speed Geometry: Precision-engineered tooth spacing pattern maximizes material extraction velocities, reducing driving tool drag spikes and load drop limits.
• High-Clarity Edge Alignment: Scoring tip configuration reduces layout boundary tear-out entirely, securing a burr-free contractor finish on both structural entry and exit faces.
• Universal Arbor System Link: Standard threaded base plate mounts rigidly onto universal large-diameter mandrels, minimizing runout wobble errors under continuous heavy loading.

What's Included

• (1) Bosch Daredevil™ 1-3/8-Inch Deep-Cut Multi-Material Carbide Hole Saw Cup
• Note: Drive arbor mandrel assembly and specialized center pilot bit are sold separately.

Technical Specifications

Pro-Tip: When cutting thick aggregate brick block fields or double-stud configurations, execute a slight back-and-forth structural rocking motion with your driver tool body. Modulating this contact tracking vector maximizes clearing velocities through the side slot extraction paths and keeps the active carbide tips running completely cool.
