If you’re sourcing for machinery building or chemical plant work, the 120-1200mm range covers most anchoring and doweling jobs, but we usually see buyers ordering around teh 300mm or 600mm lengths the most—anything over a meter gets less common.

40CR+YG8C is the materail here, so you’re getting a tougher shank than standdard 45# steel and carbide tips that hold up in rebar-heavy concrete; the head type is customizable, but we keep a standard profile in stock unless you specify otherwise.

Dimensional tolerance is held within ±0.5mm on length, which matters more for uniform stress than most people think—basically, if one bit runs long it’ll bind in the hole. We do on-site inspections and check every batch with a COA, but if you need an HPLC or hardness report, just ask when ordering.

Packaging is a plastic box per set, which is fine for storage, but don’t expect it to survive a forklift drop (usually 10-50 units per box depending on size). MOQ is 10 pieces, and our company can mix lengths in that minimum if you’re okay with slightly varied lead times.

Also, these bits aren’t great for continuous wet drilling—they’ll work, but the carbide wears faster in slurry than dry hammer drilling. JC branding is standard, but we can do custom colors if you’re ordering 100+ units or so.

What you get when ordering is the bits in a plastic box, a standard COA, and dimensional data sheet—we don’t include SDS unless you specifically request it, but we’ve got that on file.
40CR is a high-strength alloy steel that gives the bit body toughness and wear resistance, while YG8C is a carbide grade that keeps the cutting edge sharp even in abrasive concrete. Together, they handle heavy-duty masonry work without chipping or dulling quickly.
Yes, both the head type and color are customizable to fit your specific drilling needs or branding. Just let us know the details when you place the order, and we'll adjust the production accordingly.
The MOQ is 10 pieces per order, and you can mix different custom sizes within that batch—just specify the lengths you need between 120mm and 1200mm. We'll produce them all together to meet the minimum.
Yes, we can provide material certificates and test reports for the 40CR steel and YG8C carbide upon request. Since they're made to DIN and JIS standards, we also include a compliance statement if needed.
Each bit comes in a plastic box for protection during transport, and we can bundle them in larger cartons for bulk shipments. Lead time is usually around 15-20 working days for custom sizes, depending on order volume.
