CNC Tools
If you’re tired of frequently replacing broken CNC cutters and losing money from excess scrap parts, we’ve got matching tool solutions for your metal workshop.
We run an in-house carbide tool factory, covering R&D, precision grinding, and custom tool production. Our clients mainly come from Russia, Thailand, Vietnam, and other countries and regions. We carry all common CNC tool types: turning inserts, solid carbide end mills, micro drills, gear cutters, plus hydraulic and ER tool holders to match your machines.
All cutters use fine grain tungsten carbide blanks, with coating options picked to fit different metal materials. They maintain precise cuts through long hours of continuous cutting and help you reduce monthly tool costs. We can make special non-standard cutters based on your physical samples or CAD drawings, and we handle all export paperwork and shipping coordination, so overseas buyers won’t get stuck with complicated import formalities.
Ganzhou Big Brother Cutting Tools Co., Ltd. focuses on carbide industrial cutters and custom special tool production. Our newly released CM7220 inserts are made specifically for stainless steel work, solving common sticking and fast edge wear issues that most standard inserts struggle with. We keep standard tool sizes in stock for bulk orders, and we can adjust every detail of custom forming cutters to fit your unique processing workpieces.
Our CNC Carbide Tool Product Lines
We split our tools into five simple groups, covering every machining step on CNC lathes and machining centers:
1. Indexable Turning Inserts
If you run rough or medium turning jobs on carbon steel and alloy steel daily, our SNMG square inserts hold steady through long production runs without frequent edge chipping or breakdown.
For shops that balance semi-finish and fine steel turning all day long, CNMG multi-purpose inserts are a reliable everyday pick for mass part output.
Our CM7220 grade inserts were developed exclusively for stainless steel work. The customized anti-stick coating stops built-up metal clinging to cutting edges, even when machines run nonstop through full production shifts.
2. Solid Carbide End Mills & Milling Cutters
Machinists working on mold cavity profiling often reach for our bull-nose round end mills. We ship large bulk orders of these cutters to metal fabrication shops across Southeast Asia and Russia every single month.
When cutting aluminum alloy at high feed rates, our two-flute end mill sets with mirror-polished flutes deliver far smoother results. The slick flute surface prevents soft aluminum chips from welding onto the cutter body mid-cut.
We also accept custom fabrication jobs for specialty forming cutters. This includes T-slot profiling tools and thread milling cutters built to fit irregular non-standard parts. Precision gear hobbing cutters are also stocked for continuous mass production of gear blanks.
3. Carbide Drills
Straight shank twist drills cover most regular metal hole drilling tasks on CNC equipment.
Micro tiny drills are available for thin PCB boards and tiny precision hardware hole machining.
4. CNC Tool Holders & Supporting Parts
Hydraulic clamping holders, ER collet holders, and extension bars for matching milling machine spindles.
5. Custom Non-Standard Forming Cutters
A lot of complex custom workpieces cannot be processed with off-the-shelf standard cutting tools, so we fabricate all types of irregular carbide cutters built around your unique production requirements. This covers multi-step forming tools and custom grooving blades tailored to your engineering drawings or physical workpiece samples.
Practical Advantages When You Buy Our CNC Carbide Cutters
1. Stable Fine Grain Carbide Raw Material
We choose high-density fine grain carbide blanks as the base material. This material won’t deform easily under high heat and heavy cutting loads, so your tools won’t crack or chip halfway through production. We don’t use one single carbide blank for all materials; we match different grain grades for steel, stainless steel, aluminum, and cast iron separately based on your processing needs.
2. Targeted Multi-Layer Nano Coating
We provide TiN, AlTiN, and TiCN coating options. You can pick the coating type according to your main processing materials. Coated cutters can last 30% to 80% longer than uncoated ordinary cutters. The exclusive coating on CM7220 stainless steel inserts greatly reduces metal sticking problems during continuous SUS cutting.
3. 5-Axis Grinding Ensures Consistent Edge Quality
Every cutting edge gets processed by fully automatic 5-axis grinding machines. We control tolerance tightly so every batch of tools delivers the same cutting performance. The smooth finished surface on workpieces can skip extra polishing steps, which saves you labor costs on secondary processing.
4. Flexible Customization For Unique Machining Needs
There’s no fixed size limit for custom tools. Our technical team will adjust the flute shape, helix angle, chipbreaker, and coating after checking your drawings or sample workpieces. For bulk orders, we can laser print your brand logo, tool model, and applicable material on the cutter surface at no extra cost.
5. Full Export Support For Overseas Factory Buyers
Our internal team finishes all QC inspections, export document sorting, and shipping coordination. Clients from Southeast Asia, Russia, and other regions don’t need to spend extra time sorting out complicated customs clearance after goods are shipped out.

Frequently Asked Questions
Q1: How is CM7220 insert different from regular steel cutting inserts?
A: CM7220 is our newly developed grade designed only for stainless steel cutting. Its special carbide formula and unique anti-stick coating greatly reduce metal buildup during continuous SUS processing. The cutting edge rarely chips, and service life is roughly 50% longer than general-purpose inserts.
Q2: Can you make special forming cutters based on my CAD machining drawings?
A: We fully support custom forming cutters from your CAD drawings or physical workpiece samples. Our engineering team optimizes cutter structure and grinding geometry to match your unique processing demands perfectly.
Q3: Which cutter works best for mass aluminum alloy processing?
A: 2-flute solid carbide end mills with polished flute surface and anti-stick coating are the ideal pick for aluminum parts. Smooth flutes let chips evacuate quickly and avoid aluminum sticking on cutting edges during high-speed milling.
Q4: Can I order small sample cutters to test cutting performance first?
A: Small trial sample orders are available for all tool series. All sample fees you pay will be fully deducted from your formal bulk order invoice later.
Q5: Will your carbide cutters fit all mainstream CNC machine brands?
A: Standard inserts, end mills, and ER tool holders match most common CNC lathes and machining centers on the market. We can customize the inner bore, shank, and clamping size for special brand equipment if you need.
Q6: Do you offer re-sharpening service for worn carbide cutters?
A: We provide professional edge re-grinding service for end mills and forming cutters. Refurbishing dull cutters restores full sharpness and helps you save repeated tool purchasing costs.
