You're looking at a DIN 8035 spec, so the shank geometry and overall dimensoins are held to tighter tolerances than off-brand stuff — that matters a lot when you're running multiple bits through a Bosch or Hilti rotary hammer and you don't want binding or wobble at 500 RPM. We've seen customers burn through cheap bits in a day on granite; the YG8C tungsten carbide tip, brazed at 1120°C, is what keeps the edge from rolling over after 50 holes or so in reinforced concrete.
It's basically 40Cr steel for the body — that's a Chinese grade roughly equivalent to AISI 5140 — and the milled flutes come in S2 or S4 patterns, so for general masonry drilling most guys pick the S2 for faster dust removal, while the S4 is better for deeper holes where chip packing is an issue. 4mm up to 30mm diameter range, lengths form 110mm to 1000mm (we usually stock up to 600mm, but the longer ones need a 2-week lead time). Surface is sand-blasted, which is fine for anchor drilling but don't expect a mirror finish — it's functional.
Flat tip geometry, so it self-centers well on the initial contact point — no walking across tile or hard aggregate. What it's not great for is rebar-heavy demolition work; the carbide will chip if you hit steel dead-on repeatedly. 1.5 meters per bit is about average life in standard concrete before resharpening, maybe 20-30% less in very hard granite (6000 psi or higher sand aggregate).
Packaging comes as PVC tray inside a carton — MOQ is typically 500 pieces for mixed sizes, though our company can do 200 for a single diameter/length if you're testing the waters. HS code 8207509000 covers hammer drill bits, so customs clearance is straightforward for most bulk orders.
Anyway, the shank inlet is machined to leave a slight taper at the entry — we've had fewer complaints about locking pins wearing out compared to bits that are ground flat at the back, which Hilti and Makita users appreciate. Actually, one thing that isn't in the spec sheet: carbide grain size runs about 0.8-1.2 microns, giving a good balance between wear resistnce and toughness for intermittent hand-held drilling.
We typically require a MOQ of 500 pieces per size, but we can be flexible for first-time orders — just reach out to discuss.
We can provide a Material Test Certificate for the 40Cr steel and YG8C carbide, plus a DIN 8035 compliance statement. Just let us know what your buyer needs.
Yes, we can customize flute types (S2 or S4) and lengths up to 1000mm, but that will affect lead time and pricing. Send us your specs for a quote.
Absolutely, the SDS Plus shank fits all listed brands including Hilti, Makita, Bosch, and others. No adapter needed.
Standard packaging is a PVC box inside a carton. For bulk export, we can also do polybag + carton to save on shipping costs.
