Diablo Tile Drill Bit DMANS1050 3/8 x 3 3/4 Inch (3 Flat Shank Carbide Tipped Rotary Mode Porcelain Tile Ceramic Stone Glass Anchor Drilling)

Diablo DMANS1050 3/8-Inch x 3-3/4-Inch Tile, Stone, and Glass Carbide Drill Bit

The Diablo DMANS1050 is a 3/8-inch diameter by 3-3/4-inch overall length carbide-tipped drill bit engineered with a 3-flat shank for rotary-only drilling through fragile tile, natural stone, and glass. Manufactured with a heat-hardened tungsten carbide tip that delivers extended service life over standard tile bits, this precision cutter uses a multi-ground tip geometry to prevent surface walking and cracking on glazed porcelain and ceramic. Designed for tile setters, plumbers, and glass fabricators operating corded or cordless rotary drill drivers, its non-slip 3-flat shank ensures steady torque transmission without chuck slippage.

Best Used For:

• Bathroom Tile Plumbing Anchor Installation: Boring clean 3/8-inch holes through ceramic and porcelain shower tiles for grab bar, towel rack, and glass enclosure anchors.
• Granite & Marble Countertop Hardware Mounting: Penetrating dense stone slabs and vanity tops without edge blowout or face glaze cracking.
• Glass Panel & Plate Sheathing Fastening: Executing rotary-mode drilling through sheet glass, slate tile, and mirror panels without material shattering.

Key Performance & Safety Features

• Multi-Ground Precision Carbide Tip: Formulated tungsten carbide tip provides aggressive initial penetration to eliminate surface walking on smooth glazes.
• 3-Flat Anti-Slip Shank Profile: Three ground flats lock firmly into standard 3/8-inch and 1/2-inch drill chucks to eliminate rotational spinning under load.
• Heat-Treated Tip Brazing Process: Advanced bonding metallurgy preserves carbide tip attachment during friction heat buildup in dense ceramics.
• Rotary-Only Mode Operation: Optimized specifically for non-impact rotary drill drivers to safeguard delicate glass and stone substrates against fracturing.
• Clean Hole Margin Finish: Sharp cutting angles sheer through brittle surfaces to create chip-free entry and exit margins.
• Universal Drill Driver Compatibility: Performs efficiently in standard corded drill presses and 18V/20V cordless handheld drill drivers.

• (1) Diablo 3/8" x 3-3/4" Tile, Stone, & Glass Carbide-Tipped Drill Bit (DMANS1050)

Technical Specifications

Pro-Tip: Keep drill speeds low and apply light, constant pressure with periodic water lubrication when drilling porcelain tile to control heat and extend the sharpness of the multi-ground carbide tip.
