Masonry Drill Bit Set 5pc 4-10mm

5PC masonry drill bit set Drill bits in the set: Ø4mm Ø5mm Ø6mm Ø8mm Ø10mm Application: The drill bits in the set are used to drill into masonry, thanks to the uniquely designed TCT (tungsten carbide tipped) point. A percussion (hammer action) drill with a 3 jaw chuck is required. Preset the depth gauge on the drill to achieve the correct depth before drilling into walls. TIP: Have a wall scanner (detector) ready before drilling into walls. CAUTION: Do not use the drill bits in the set with a rotary hammer. The impact energy will break the conversion chuck.
