About ZCC·CT Indexable Drill Inserts
ZCC·CT (ZCC Cutting Tools) indexable drill inserts are precision ground carbide inserts for U-drill (spade drill) and high-feed drilling operations on machining centers. The line is dominated by the WCMX family — the global industry-standard 80° trigon insert geometry used by every major insert manufacturer (Mitsubishi, Sandvik, Kennametal, Iscar, Tungaloy, TaeguTec, Walter). WCMX inserts mount on indexable U-drill bodies covering drilling diameters from 12 mm to 60 mm with interchangeable insert sizes.
ZCC·CT's drill insert grades — YBC (CVD-coated steel), YBD (CVD-coated cast iron), YBG (PVD universal), YBM (PVD stainless), YD (uncoated aluminum), and the YBG25x high-temp series — are specifically formulated for the high cutting forces and exit-chip thinning that drilling requires. CNCHome-Beyond is an authorized ZCC·CT distributor; orders placed before 3 PM China time ship same-day from our Hangzhou warehouse with DHL/UPS/FedEx express delivery in 3-7 business days.

About ZCC·CT grade selection for drilling: Drilling generates the highest mechanical and thermal stress of any turning operation. The cutting edge experiences full engagement, exit-chip thinning, and the entry/exit shock loads. ZCC·CT's grade selection is optimized for this: YBC (CVD) grades are the workhorse for steel because the thick coating resists wear; YBD (CVD) grades for cast iron's abrasive chips; YBG (PVD) grades for universal and stainless (thin coating keeps edge sharp for low thrust force); YBM for stainless where work-hardening resistance matters; YD (uncoated) for aluminum. For high-feed WPGT or ZOHX drilling, use the extra-tough variants (YBC302, YBG252, YBM351).
WCMX Chip-Breaker Reference (2 Variants)
WCMX uses 2 chip-breaker geometries distinguished by suffix on the part number:
| Chip-Breaker | Application | Feed | Best With Series |
|---|---|---|---|
| PG (precision ground) | Sharp edge for finishing, low thrust force | 0.05-0.15 mm/rev | WCMX-PG (precision hole, finishing pass) |
| 53 (flat top, no chip-breaker) | General purpose drilling, balanced | 0.05-0.20 mm/rev | WCMX-53 (workhorse, most common) |
WPGT uses a different chip-breaker: ZSR = ZCC·CT Strong Roughing, for high-feed drilling in tough materials (heavy interrupted cuts, cast iron drilling at high feed).
ZOHX uses two chip-breaker variants: GM (General Medium) and GF (General Fine). ZOHX is a high-feed geometry, so the chip-breaker focuses on chip control at elevated feed rates.
How to Choose a ZCC·CT Drill Insert
Step 1: Match the series to the operation. For 80% of U-drill applications, choose WCMX (industry standard 80° trigon). For high-feed drilling with chip-breaker, choose WPGT (ZSR chip-breaker). For premium high-feed drilling with deep cuts, choose ZOHX (4 sizes, premium grade YBG252). For round-insert high-feed drilling, choose ROHX.
Step 2: Match the IC size to the drill body. WCMX-03 fits 12-17 mm drill bodies, WCMX-04 fits 17-25 mm, WCMX-05 fits 25-35 mm, WCMX-06 fits 30-42 mm, WCMX-08 fits 40-60 mm. WPGT-05/06/08 covers 17-45 mm range. ZOHX-12/16/25/30 covers 12-30 mm range.
Step 3: Match the grade to the workpiece material. Steel → YBC151 (finishing) or YBC301 (roughing). Stainless → YBG202 (workhorse) or YBM351 (heavy). Cast iron → YBD151 (universal) or YBD252 (heavy). High-temp alloys (Inconel, titanium) → YBG205 or YBG212. Aluminum → YD101 (sharp uncoated).
Step 4: Match the insert to the drill body. WCMX fits industry-standard U-drill bodies from all major brands. ZCC·CT WCMX inserts fit Tungaloy TungDrill, Mitsubishi UD series, Sandvik R390-11 series, Kennametal KCP25 series, Iscar IC9080 series, TaeguTec TDC series, Walter D3120 series — all are dimensionally interchangeable on the same drill body. CNCHome-Beyond carries compatible aftermarket drill bodies at 30-50% below OEM — see our tool holder guide and Insert Holder Selector.

Frequently Asked Questions
What is the difference between WCMX and WPGT drill inserts?
Both are 80° trigon drill inserts, but optimized for different operations. WCMX has a precision-ground edge (PG) or flat top (53) and is the general-purpose U-drill workhorse. WCMX has 2 cutting edges per insert and is the most economical choice. WPGT has the ZSR (Strong Roughing) chip-breaker on both sides, optimized for high-feed drilling in tough materials like cast iron and high-temp alloys. WPGT has 4 cutting edges per insert (2 per side) but is more expensive per insert. Use WCMX for 80% of U-drill applications; use WPGT for high-feed heavy-duty drilling in cast iron or Inconel.
What is the difference between YBC and YBG grades for drilling?
Both are high-quality coated grades, but optimized for different conditions. YBC (CVD coated, TiCN + Al2O3) grades are optimized for steel drilling — the thick coating resists wear on the cutting edge during the long chip-flow contact in drilling. YBG (PVD coated, TiAlN) grades are optimized for universal/stainless — the thin coating keeps the edge sharp for low thrust force. Use YBC for steel drilling; use YBG for stainless, high-temp alloys, or mixed-material work. For deep hole drilling (5D+), use the extra-tough variants (YBC301, YBG252, YBM351) to handle the long chip evacuation and exit-chip thinning.
What is the equivalent of ZCC·CT WCMX 040208R-53 YBG202 in other brands?
ZCC·CT WCMX 040208R-53 YBG202 is the industry-standard U-drill insert (1/2" IC, 0.8mm nose, 80° trigon, 53 flat top chip-breaker, PVD universal workhorse grade). Direct equivalents: Mitsubishi WCMX 040208R-53 US7020, Sandvik R390-11 04M0-04M GC4325, Kennametal KC7315 KCP25, Iscar IC9080 WCMX 04. All are dimensionally interchangeable on the same U-drill body. For grade cross-reference, see our Insert Grade Cross-Reference Tool.
What is the ZOHX series and when should I use it?
ZOHX is ZCC·CT's premium proprietary high-feed drill insert line, with only 4 SKUs covering 12-30 mm range. The ZOHX geometry is designed for high-feed drilling (typically 0.15-0.30 mm/rev, vs standard 0.05-0.15 mm/rev) with deeper cuts. Each ZOHX insert costs $280-$423 (highest in catalog) but delivers 2-3x the tool life per edge in high-feed applications due to the unique geometry. The standard grade is YBG252 (PVD universal heavy). Use ZOHX for production line high-feed drilling where the per-edge cost is offset by longer tool life and reduced changeover time. For general U-drill applications, the cheaper WCMX with YBC/YBD grade is the better choice.
What is the difference between WCMX and WCMT?
WCMX has a 7° positive clearance angle, making it a positive drill insert suitable for general U-drill applications on standard machining centers. WCMT has a 0° clearance angle, making it a negative drill insert for heavy-duty drilling with maximum edge strength on rigid machines. Most U-drill applications use WCMX (positive) because the 7° clearance reduces thrust force and allows higher feed rates. WCMT is reserved for very heavy drilling where chip evacuation is critical. ZCC·CT's catalog lists WCMX inserts; WCMT is available from other brands (Sandvik, Mitsubishi) for special applications.
What is the minimum order quantity for ZCC·CT drill inserts?
Sample orders start at 1 piece for grade validation. Standard production orders are 10-50 pieces per item. Bulk pricing tiers: 2-9 pieces 6% off, 10+ pieces 12% off (auto-applied at checkout). For custom IC sizes or chip-breakers not in our standard catalog, MOQ is 200 pieces with 6-8 week lead time from ZCC·CT Zhuzhou. See our warranty and return policy for details on grade validation samples.
