7/8" Carbide Masonry Bit for Anchors
This 7/8 inch carbide-tipped bit drills brick, concrete and sandstone using a standard portable electric drill. The 1/2 inch round shank fits common three-jaw chucks. Black oxide finish resists corrosion during storage and use. Carbide tips are brazed to tough steel bodies for durability in abrasive materials.
Replaces Worn Bits When Anchor Clearance Matters
Switch to this bit when an old masonry drill no longer cuts cleanly or when the hole must be slightly larger than the nominal size. The oversized carbide tips create clearance for anchor screws, expansion shields and toggle bolts without a separate reaming step. Wide spiral flutes eject dust quickly in softer masonry so the bit does not bind.
Sustained Drilling in Soft Masonry Without Binding
Wide flutes keep the hole clear during continuous drilling in brick or sandstone, reducing heat build-up and friction. The 118 degree conventional point centres the bit reliably at the start of each hole. Carbide tips maintain their edge longer than plain steel when drilling multiple anchor locations in a single session.

Questions about this item
What size drill chuck does the 1/2" round shank require?
The bit has a 1/2" round shank, so it fits any drill chuck that accepts a 1/2" shank.
How do I avoid the carbide tip walking when I start the hole?
Use a centre punch to mark the exact spot, then start drilling at low speed with steady pressure until the 118° point bites.
When should I replace the bit instead of continuing to use it?
Replace it when the carbide tip chips, the cutting edges dull enough to slow progress, or the flutes clog and overheat the steel body.
