Diablo DMARG1020 5/32-Inch SPEEDemon Hex Shank Masonry Drill Bit 5-Pack

The Diablo DMARG1020 5/32-Inch SPEEDemon Hex Shank Masonry Drill Bit 5-Pack is a high-speed drilling accessory set engineered for boring clean, anchor-ready holes through concrete, brick, block, granite, and stone. Built with an Impact Strong 1/4-inch hex shank and a multi-ground Grip Point Tip PLUS, each 6-inch bit (3-inch working length) attaches securely to cordless impact drivers and hammer drills. Featuring heat-treated Dura-Carbide tips and optimized U-flute dust extraction channels, this 5-piece bit set solves tip slippage, thermal degradation, and slow chip removal challenges during masonry fastener installation.

Best Used For:

• Concrete Screw Anchor Installation: Drilling precise 5/32-inch pilot holes into poured concrete slabs and foundation walls for masonry screw anchors.
• Granite & Stone Slab Fastening: Boring clean holes through natural granite countertops, marble tiles, and stone pavers without surface fracturing.
• Brick & Block Wall Anchoring: Executing rapid hole drilling into clay brick mortar joints and cinder blocks using high-torque impact drivers.

Key Performance & Safety Features

• 4X Extended Carbide Life: Diablo-manufactured carbide tips withstand severe impact forces and thermal stress to deliver up to 4 times longer service life.
• Grip Point Tip PLUS Geometry: Multi-ground tip design eliminates bit wandering on hard surfaces for aggressive, precise hole starts.
• Impact Strong Hex Shank: 1/4-inch hex shank fits 1/4-inch impact drivers and standard drill chucks, preventing slippage under high torque loads.
• Optimized U-Flute Design: Rapidly clears abrasive masonry dust away from the cutting tip to maintain cooler operating temperatures.
• Higher Runtime Efficiency: Low-friction flute geometry drives more holes per battery charge on cordless hammer drills and impact drivers.

Technical Specifications

Pro-Tip: Use a steady, straight-line feed pressure without tilting the driver when drilling 5/32-inch pilot holes into hard granite to allow the U-flute to evacuate dust efficiently and prevent bit binding.
