BEYOND 3D Indexable U-Drills | WCMX WC03-WC08

BEYOND 3D Indexable U-Drills with WCMX Trigon Inserts — 15–60mm, 69 SKUs

Shop 69 genuine BEYOND 3D indexable U-drill bodies covering the full 15–60mm diameter range with 0.5mm or 1mm increments. All bodies accept industry-standard WCMX / WCMT trigon inserts in five sizes (WC03 / WC04 / WC05 / WC06 / WC08), giving 3 usable cutting edges per insert for low cost-per-hole. Bodies are forged from 20CrMnTi alloy steel, vacuum-quenched, and nickel-plated for corrosion resistance. Each drill features high-pressure dual internal coolant channels and optimized spiral flutes for forced chip evacuation in steel, stainless, and cast iron.

BEYOND WC U-Drill Model Code Nomenclature

Each BEYOND WC drill body follows a 5-segment model code. Example: WC40-3D-SD60-WC08 = WC trigon style / 40mm shank / 3×D depth / 60mm cutting diameter / fits WC08 insert.

69 SKUs by Shank Series and Insert Size

The 69 SKUs split across 4 shank series and 5 insert sizes. The shank determines the upper diameter limit your machine can accept; the insert size determines which WCMX trigon index you need to buy separately.

Insert size distribution: WC03 (11 SKUs) + WC04 (8) + WC05 (12) + WC06 (19) + WC08 (19) = 69. Each drill body ships without inserts — you must order the matching WCMX trigon insert separately.

Recommended Cutting Parameters

Baseline settings for 3D U-drill operations. Adjust based on your insert grade, machine rigidity, and workpiece condition.

For all diameters, high-pressure internal coolant (≥ 7 bar / 100 psi) is mandatory for chip evacuation. Spindle speed N = (Vc × 1000) ÷ (π × D), where D is the cutting diameter.

Compatible WCMX Trigon Inserts (Sold Separately)

The drill bodies in this collection accept industry-standard WCMX / WCMT trigon inserts. Use the table below to match your body SKU to the correct insert code.

Inserts are dimensionally interchangeable across all WCMX-spec manufacturers including Sandvik, Mitsubishi, Kennametal, Iscar, TaeguTec, ZCC·CT, Kyocera, and Walter. Search the broader indexable insert catalog at the Premium Carbide Inserts aggregate for the matching insert grade.

Typical Applications

• Structural steel plates (15–60mm thick) — construction, shipbuilding, bridges, towers
• Flange drilling (steel / stainless / cast iron flanges, ANSI / DIN / JIS standard)
• Hydraulic valve blocks (cast iron / steel) — main ports, cross-drilled passages
• Gearbox housings (cast iron GG25 / FCD450) — bearing bores, bolt circles
• Heat exchanger tube sheets (stainless 304 / 316) — high hole-count, tight pitch
• Heavy machinery frames (low-carbon steel plate) — large bolt holes >30mm
• Pump and compressor bodies (cast iron / steel) — medium-bore main ports
• Mining and quarry equipment (hardened wear-resistant steel) — bracket and pivot holes

BEYOND 3D U-Drill FAQ

Q: Does the BEYOND drill body come with the WCMX inserts?

No. The drill body ships without inserts — you must order the matching WCMX trigon insert separately. Each body includes the insert screws and a Torx wrench. Insert size is encoded in the SKU suffix (e.g. WC40-3D-SD60-WC08 = fits WC08 / WCMX 08 insert).

Q: What is the difference between 2D, 3D, 4D, and 5D depth ratios?

The D-ratio is the maximum drilling depth expressed as multiples of cutting diameter. 2D/3D (this catalog) = maximum rigidity, best for large diameters, heavy roughing, and machines with high torque but limited RPM. 4D = the universal standard for general-purpose drilling. 5D+ = long-reach drilling that requires reduced feed rates and ultra-high coolant pressure to prevent chip packing and drill breakage. Choose 3D for safety and rigidity; choose 4D/5D when the part geometry requires it.

Q: Can I use WCMX inserts from other brands (Sandvik, Mitsubishi, Kennametal) in BEYOND drill bodies?

Yes. The BEYOND WC drill body uses the standard ISO 9766 WCMX trigon insert interface, so any WCMX insert of the matching size code (WC03, WC04, WC05, WC06, WC08) will physically fit and clamp correctly. You can mix and match insert brands based on availability, price, and grade preference. Browse the full insert catalog at the Premium Carbide Inserts aggregate.

Q: What machine power is required for 3D U-drilling?

Approximate spindle power requirements: 15–25mm diameter = 5–10 kW, 25–40mm = 10–20 kW, 40–60mm = 20–40 kW. Torque capacity is more critical than peak power for U-drills because the cutting diameter drives the torque load cubically. If your machine cannot deliver the rated torque, the drill will stall in mid-cut, which can damage both the body and the workpiece.

Q: Are BEYOND drill bodies good for stainless steel?

Yes — BEYOND 3D U-drills work well in stainless 304 / 316 / 17-4PH when paired with a PVD-coated WCMX insert (e.g. KORLOY PC9030, Mitsubishi VP15TF, or Sandvik GC1040). Use the cutting parameters in the table above as a starting point. Reduce cutting speed by 20% versus carbon steel and ensure high-pressure internal coolant delivery (minimum 7 bar / 100 psi).

Q: What is the typical hole tolerance and surface finish from a 3D U-drill?

Hole tolerance is typically IT10–IT11 (approximately +0.15 to +0.30mm on diameter), and surface finish is typically Ra 1.6–3.2 μm. For tighter tolerances or better surface finish, follow up with a boring head or finish reamer. For roughing-only applications (typical for U-drills), the as-drilled tolerance is acceptable for most assembly bores and fastener clearance holes.
