Avanti Pro Masonry Drill Bit PMAPC1050 3/8 Inch x 6 Inch (Straight Shank Carbide Tipped Steel Dual Flute Brick Cinder Block Concrete Boring)

Heavy-Duty 3/8 Inch x 6 Inch Carbide Tipped Straight Shank Masonry Drill Bit

The Avanti Pro PMAPC1050 Masonry Drill Bit serves as an impact-rated rotational penetration cutter engineered to drill 3/8-inch anchor and conduit clearance holes up to 4 inches deep into brick, cinder block, and poured concrete. Constructed with a reinforced tungsten carbide tip brazed onto a high-strength alloy steel body, this 6-inch overall length bit operates on variable-speed corded and cordless rotary drills. Featuring a 10mm (0.39-inch) straight shank that locks firmly into standard 1/2-inch drill chucks, the bit incorporates dual dust-extraction flutes that channel masonry slurry out of the borehole to eliminate binder drag and thermal stress during continuous drilling passes.

Best Used For:

• Medium-Duty Masonry Fastener Installation: Boring uniform 3/8-inch diameter holes for drop-in anchors, expansion bolts, and sleeve anchors in concrete walls and slabs.
• Electrical Conduit & Wire Pass-Throughs: Drilling 4-inch deep penetration holes through hollow cinder blocks and mortar joints for wiring or utility runs.
• Rotary Drill Fastening Projects: Executing clean, chatter-free masonry drilling runs using standard variable-speed rotary drills in non-hammer mode.

Key Performance & Safety Features

• Brazed Tungsten Carbide Tip: Impact-rated carbide tip maintains razor-sharp cutting edges when boring into highly abrasive aggregate and brick.
• Dual Flute Slurry Removal: Deep spiral flute geometry rapidly clears pulverized dust and debris from the borehole to prevent binding.
• 10mm Straight Shank: Universal 0.39-inch straight shank provides broad chuck clamping surface in standard corded or cordless drills.
• 4-Inch Usable Drilling Depth: 6-inch total length delivers a full 4 inches of usable drilling depth for long structural anchors.
• Impact-Rated Steel Alloy Core: High-strength steel shaft absorbs rotational torque and impact energy for extended tool life in tough materials.

Technical Specifications

Pro-Tip: When boring 3/8-inch anchor holes in dense concrete, apply moderate forward pressure and allow the tungsten carbide tip to chip the material without forcing the drill. Periodically retracting the bit clears trapped dust from the dual flutes, preventing overheating and extending carbide cutting life.
