manufactures the 3-cutter full carbide head SDS-Plus drill bit as a factory-direct OEM and private-label program. The cutting head is a single sintered piece of tungsten carbide ground to three edges at 120° around a self-centering tip, then resistance butt-welded to a hardened 40Cr body — no brazed inserts, no silver-braze seam to fatigue under impact. Range Ø3–20 mm.

We build this geometry full-carbide-head only. The brazed 3-plate version (discrete carbide segments at 120°) is a different construction we deliberately do not offer; our 3-cutter is the one-piece sintered head — the small-diameter single-piece construction the premium brands also use at SDS-Plus sizes. It is the same 120° geometry Heller markets as its Trijet tip, supplied direct-from-factory at OEM economics under your brand. U Flute Single Tip Masonry Concrete Drill Bit SDS Plus Type

Why specify the 3-cutter full carbide head
Three carbide edges keep at least two engaged at all times, so the bit centers itself, drills a near-perfectly round and calibrated hole for anchors, and stays steady when it grazes rebar. Because the one-piece head holds its gauge as it wears, the hole stays calibrated and the bit is less likely to bind on a bar. The signature application is composite steel decking: the full carbide head drills the concrete and punches through the light-gauge steel deck plate in one pass, with no bit change.  SDS Plus Shank Drill Bit Concrete Rotary Hammer Drill Bit
