  • Drill concrete, brick or block with a 10-piece steel bit set
  • 5/32 inch diameter suits precise anchor and fastener holes
  • 4-1/2 inch length reaches deeper into masonry walls
  • Steel construction resists wear during repeated impact drilling
  • Manufacturer part number 63493 identifies the exact replacement pack

Concrete drilling set

This ten-pack of steel drill bits is designed for boring into concrete, brick or block. It suits tradespeople and DIY users who need multiple bits for repetitive masonry work. The 5/32 inch by 4-1/2 inch size handles common anchor and fastener pilot holes.

Heat and wear in use

Friction in hard masonry generates heat at the cutting edges during normal drilling. Steady pressure and periodic withdrawal help control temperature and clear dust from the flutes. The steel body resists deformation under typical handheld drill loads.

Pack quantity and storage

Ten bits in one package reduce the risk of downtime when a bit dulls or breaks on site. The uniform diameter simplifies bit changes without adjusting drill chuck settings. The compact pack fits easily in a tool bag or job box for daily access.

Questions about this item

How do I fit the 5/32" x 4-1/2" bit into my hammer drill, and what step do people often miss?

Insert the straight shank fully into the chuck, tighten securely, and set the drill to hammer mode; the step most users miss is engaging hammer action before starting.

When will the 10-pack of steel concrete bits need replacement?

Replace individual bits when the carbide tip wears down or the flutes clog so dust no longer clears; lifespan depends on the hardness of the concrete, brick or block being drilled.

What limit appears first during continuous drilling with these bits?

Heat buildup at the tip is the first limit; pause periodically to let the steel cool and clear debris from the flutes to maintain cutting speed.
