Learn more by watching our Alpha SP055160G | 5.5 x 160mm SDS Plus German 2 Cutter Masonry Drill Bit video.
The Alpha SP055160G is a 5.5mm SDS Plus masonry drill bit fitted with a German two-cutter carbide head. It measures 160mm overall length with a 100mm flute length and is made in Germany. The SP055160G suits all masonry applications, including hardened concrete, and is intended for SDS rotary hammer impact drills.
Hardened concrete sits at the harder end of the masonry range that fixing work has to cover. The SP055160G head is a centring chisel head feeding a multi-flute spiral, the geometry specified for drilling capacity. The bit is rated for all masonry applications including hardened concrete, so slab, lintel and blockwork fixings sit inside that range.
PGM-certified hole accuracy applies to the SP055160G, covering how closely the drilled hole matches its nominal size. The head also carries secondary cutters, specified to protect the bit if it strikes reinforcement mid-hole. Both sit alongside a dynamic chisel-shaped head design on this bit.
The SP055160G is a two-cutter bit, and four-cutter heads cover REO concrete. Its secondary cutters protect the bit on incidental reinforcement contact, which is not a rating for drilling reinforcement. The SDS Plus shank also means it will not hold in a keyless or three-jaw chuck.
(SP055160G)
The SP055160G has an SDS Plus shank and is intended for SDS rotary hammer impact drills. It will not clamp in a keyless or three-jaw chuck. Any rotary hammer with a standard SDS Plus chuck will accept the shank.
A two-cutter head carries two carbide cutting edges across the tip. Two-cutter SDS Plus heads cover hardened concrete and masonry, while four-cutter heads cover REO concrete. The head on this bit is a German two-cutter design with a centring chisel tip.
Four-cutter SDS Plus heads cover REO concrete, not two-cutter heads. The SP055160G carries secondary cutters specified to protect the bit if it strikes reinforcement, which is protection on contact rather than a rating for drilling through steel.
The SP055160G measures 160mm overall with a 100mm flute length. The fluted section is the working length that clears dust from the hole, so usable hole depth is governed by that 100mm figure rather than the 160mm total.
PGM certification covers hole accuracy, meaning how closely the drilled hole matches its nominal diameter. This 5.5 x 160mm SDS Plus bit carries PGM-certified hole accuracy. The certification applies to the drilled hole rather than to bit lifespan.
Germany is the country of manufacture for this SDS Plus two-cutter masonry drill bit. The German designation in the product name refers to that.
