The Diablo Rebar Demon 1/4 in. x 8 in. Carbide Hammer Drill Bit with SDS-Plus Shank is engineered for serious masonry and reinforced concrete work. Built with a durable carbide tip and a rugged SDS-Plus shank, this bit is ready to tackle hard materials and embedded rebar without frequent bit replacement.
-
Carbide construction delivers exceptional wear resistance and cutting performance in concrete, brick, block, and reinforced substrates. The carbide tip stays sharp longer, so you can drill more holes between bit changes.
-
SDS-Plus shank ensures quick, secure engagement with compatible hammer drills, minimizing wandering and chatter for cleaner, more accurate holes.
-
8" overall length with a 6" flute optimizes deep-hole drilling and efficient chip removal, helping you maintain steady progress when anchoring or routing through thick masonry.
-
1/4" diameter is a common choice for anchor and fastener installations in concrete, masonry walls, and floors—especially where rebar is present or expected.
-
25-pack, carded packaging keeps your job kit stocked and organized, so you’re ready for a day of continuous drilling without frequent repurchases.
-
Designed for Rebar Demon performance—a Diablo lineage built to handle the toughest reinforced concrete scenarios with reliability you can count on on the jobsite.
Who should use this bit? Professional electricians, plumbers, HVAC installers, and general contractors who routinely drill through reinforced concrete, masonry, and concrete with embedded rebar will benefit from the bit’s longevity and precision. It’s ideal for creating anchor holes for heavy hardware, securing conduit or piping, and penetrating tough masonry in new construction or retrofit projects.
How this bit stands apart from everyday masonry bits: its carbide tip and SDS-Plus compatibility deliver longer life and steadier performance in demanding environments, reducing downtime caused by dulling or bit slippage. When paired with a compatible hammer drill, you’ll experience cleaner starts, straighter holes, and fewer bit changes—especially in rebar-rich concrete.
Tips for maximizing performance: use the hammer drill in bit-friendly modes, apply steady pressure without forcing the bit, keep the bit cool to extend life, and start with a light pilot or perforate slowly before advancing to full-depth drilling. Clean the hole to remove dust and debris between passes for more accurate placement and anchor seating.
