SDS-Plus / SDS-Max 2-cutter centering-tip drill bits (IZ carbide geometry)

A raised nipple-style apex carries the first contact and locates the hole before the two main edges engage, so the bit starts on-mark without a pilot punch. The CERATIZIT 46000 geometry can be ordered in CTM17-BC, a medium-grain WC-Co grade listed with ISO code BC20. Geometry and material grade are specified separately.

SDS-Plus / SDS-Max 4-cutter cross heads (5-Series)

A one-piece X-form carbide tip rather than four separately brazed plates. Because the cross is ground from a single blank, the four edges share one datum — there is no plate-to-plate misalignment to open up a gauge error, and there are no inner joint lines to become crack initiation sites. The raised centre carries first contact and locates the hole; the four arms then sweep the full gauge circle. This monobloc carbide tip is brazed into a steel head — it is not our full-head solid carbide construction (ZHPLUS-8 / ZHMAX-8), where the entire head is solid carbide and resistance-friction-welded to the steel body.

SDS-Plus / SDS-Max 4-cutter cross heads (5-Series)

In our CERATIZIT quotation, CT4 tips are listed under the 51805 series code, for example 51805-12.0 and 51805-16.0. CT4 identifies the tip style; CTM17-BC identifies the carbide grade. A one-piece X-form carbide tip with a continuous gable-roof profile: each arm slopes into the centre peak with no step transition. Because the cross is ground from a single blank, the four edges share one datum — there is no plate-to-plate misalignment to open up a gauge error, and there are no inner joint lines to become crack initiation sites. This CT4 monobloc carbide tip is brazed into a steel head — it is not our full-head solid carbide construction (ZHPLUS-8 / ZHMAX-8), where the entire head is solid carbide and resistance-friction-welded to the steel body.

SDS-Plus / SDS-Max standard 2-cutter hammer drill bits (130° roof-tip geometry)

A conventional single-plate 2-cutter hammer-drill tip with a symmetrical 130° roof profile. CERATIZIT lists style 11384 from Ø4 to Ø52 mm and marks the geometry as PGM-conforming. The catalogue ordering example combines the geometry code 11384 with CTM17-BC carbide (ISO code BC20). Geometry, grade and finished-drill certification remain separate specifications: a completed bit may carry the PGM mark only when it falls within the certified manufacturer's scope.

SDS-Plus / SDS-Max point, flat and self-sharpening chisel bodies

60Si2Mn is a silicon-manganese alloy spring steel per GB/T 1222-2016, chosen for chisel bodies because it takes a high through-hardness after heat treatment while retaining enough toughness to absorb repeated impact without cracking. The silicon content raises the elastic limit compared with plain carbon spring steels, which is what lets a heat-treated chisel body flex under hammer blows and return to shape instead of taking a permanent set.
