SDS Drill Bits Manufacturer | OEM & Wholesale Factory Supply | Zhonghuan

For importers, distributors and private-label tool brands, Zhonghuan supplies two clearly separated SDS constructions: YG8C / YG11C carbide inserts brazed in a continuous controlled-atmosphere mesh-belt furnace on hardened 40Cr / 42CrMo bodies, and one-piece full-carbide heads joined by resistance friction welding (RFW). The program covers SDS-Plus and SDS-Max geometries with private-label packaging and specification review by SKU.

SDS Supply Pages Should Sell a Buying System, Not Just a Bit

Many competitor pages target phrases like SDS drill bits manufacturer, SDS Plus wholesale, SDS Max supplier, OEM SDS drill bit factory, rotary hammer drill bits manufacturer, and concrete drill bits China. Buyers may also describe the same range as a concrete drill bit manufacturer, hammer drill bit manufacturer, or rotary hammer drill bit supplier depending on their catalog language. The useful way to win those searches is not to repeat the words. The page must help a buyer build a range: which shank, which diameter ladder, which head type, which packaging, which sample checks, and which MOQ logic.

Why Yueqing Is China's High-End SDS Drill Bit Cluster

Yueqing is the specialist Chinese manufacturing base for carbide-tipped SDS-Plus and SDS-Max drill bits. Its advantage is not the place name by itself, but the concentration of the processes this product needs: carbide-head supply, body-steel forming, flute production, brazing or welding, heat treatment, shank tooling, grinding, packaging, and export experience.

That concentration makes Yueqing the stronger starting point for a high-end SDS program. It does not make every Yueqing factory premium. Buyers still need to verify the material specification, head construction, joining route, symmetry and circular run-out, heat treatment, and final acceptance criteria. The cluster provides capability; the selected factory must prove control.

When a Buyer Actually Needs a Yueqing High-End SDS Program

• Professional or contractor channels: a broken tip, oversized anchor hole, or inconsistent reorder creates more cost than the initial unit-price saving.
• Reinforced concrete and SDS-Max: higher impact energy and rebar contact make head construction, body steel, joining, and run-out control commercially important.
• Private-label repeat orders: the second and fifth shipment must hold the same product position as the approved sample.
• A complete distributor range: SDS-Plus 2-cutter, 4-cutter, full-carbide heads, SDS-Max, chisels, sets, and packaging must work as one coherent series.

The demand is not for “a more expensive Chinese bit.” It is for fewer returns, a range that can be reordered without changing its market position, and a private-label series that gives the distributor room above the lowest-price shelf. Zhonghuan uses its Yueqing base to turn that need into a specification-led SDS program: head type, diameter ladder, target application, packaging, and acceptance points are defined before the quote.

Opening Range for Distributors

Which Head for Which Material

The head geometry should match the material, not the brand. The simple rule: soft and hollow masonry wants a 2-cutter for speed; reinforced concrete wants four edges or more to survive rebar; hard abrasive rock and deep SDS-Max work wants a multi-segment head; the smallest repeated-rebar sizes want a full carbide head. This matrix maps our heads to the common base materials so a distributor can spec the right line per channel.

●●● best choice · ●● workable · ● limited · — not advised. Match grade to the work too: tougher high-cobalt for rebar, finer-grain wear-resistant for abrasive stone.

• 2-cutter (self-centering tip) — plain concrete, brick, block and masonry where rebar is not the issue; clears dust faster and drills more holes per charge.
• 4-cutter cross (ZHMAX-5X) — reinforced concrete with frequent rebar; four edges share the impact and shrug off the steel.
• Multi-segment 4-cutter (ZHMAX-7) — hard abrasive rock, deep holes and heavy SDS-Max work (Bosch SDS max-7 class).
• Full carbide head (ZHMAX-8) — the smallest diameters under repeated rebar contact, where maximum carbide volume pays back.

Head choice also drives exit quality, not just speed. On through-holes the last few millimetres of concrete have no backing, so a single-line 2-cutter tends to blow out a larger exit cone, while a 4-cutter cross or multi-segment head spreads the impact and a self-centering tip keeps the exit round. That protects effective embedment and anchor pull-out on the back face — so for distributors whose customers do through-anchoring or care about exit finish, spec the cross or multi-segment head, not the cheapest 2-cutter.

SDS Procurement Fields That Define the Program

The buying decision is built around shank system, diameter matrix, two-cutter or four-cutter architecture, carbide construction, packaging, sample validation and MOQ structure. Zhonghuan maps these fields into a quote-ready SDS-Plus and SDS-Max program.

RFQ Checklist

• Shank system: SDS-Plus, SDS-Max, or mixed program.
• Diameter and length ladder by market: anchors, general masonry, deep holes, or demolition support.
• Head design: 2-cutter, 4-cutter, cross tip, rebar-aware geometry, or value line.
• Carbide and body: carbide grade, brazing method, body steel, flute type, and shank marking.
• Target price position: Yueqing repeatable quality line or low-cost retail line.
• Packaging: bulk, PVC pouch, plastic tube, blister, color box, plastic case, or mixed set.
• Sample checks: drilling speed, diameter, shank fit, runout, rebar contact, and packaging drop resistance.

Procurement Terms at a Glance

Before the quote, importers, distributors, and private-label tool brands usually want the same six numbers. This is what our OEM program looks like for this product family.
