Factory-Engineered Low-Drag Cutting
Manufactured in-house with automated laser plate cutting and multi-roller hydraulic tensioning (dynamic runout ≤0.08mm), the Nakamura PG-5 165×20×48T eliminates cutting chatter and blade deflection on high-torque 18V/20V cordless platforms.
By replacing non-functional, bulky carbide mass with our proprietary 3.0×1.3mm sub-micron micro-grain tips, we optimize the raw material BOM at the factory level-delivering industrial multi-material durability at an unbeatable wholesale margin for B2B distributors. The ultra-compact tooth profile reduces kerf friction by up to 42%, boosting cordless battery runtime by 30% while cutting clean through framing lumber with embedded construction nails, 1.5mm steel track, and rigid plastics without motor drag or tip detachment.

Jobsite Pain Points vs. Engineering Solutions
Motor Bogging & Battery Drain: 3.0×1.3mm tooth volume reduces cutting resistance, lowering motor amp draw under heavy feed rates.
Tooth Fracture on Hidden Steel Nails: Micro-grain carbide formulation eliminates internal sintering voids, absorbing shock loads without chipping.
Rough Cuts Across Mixed Materials: Dual-bevel BC (Bevel & Chisel) tooth geometry cleanly shears wood grain and clears metal swarf without burrs.
Target B2B Buyer Profiles
Framing & Demolition Crews
Cut framing lumber, subflooring, and formwork without stopping to swap blades every time a nail appears.
Commercial Fitout Contractors
Keep cordless circular and plunge saws running all day on jobsites before temporary power is connected.
Wholesalers & Private-Label Importers
High-turnover SKU positioned with strong distributor margins against expensive premium-brand multi-cutters.
Manufacturing Strengths & Factory OEM/ODM Capabilities
Automated Tri-Metal Brazing & CNC Grinding: Robotic induction brazing applies high-tensile silver-copper-silver sandwich braze alloy to cushion torsional impacts, while 6-axis multi-axis CNC grinding centers maintain sub-micron cutting-edge uniformity across large production runs.
BOM Optimization & Direct Wholesale Pricing: In-house sintering of compact 3.0×1.3mm carbide tips reduces raw metallurgical waste, enabling factory-direct wholesale pricing that yields 25%–35% higher distributor margins compared to legacy bulky-tip blades.
Frequently Asked Questions (FAQ)
Q: Will the compact 3.0×1.3mm tooth tip snap off or strip when hitting hardened 3-inch framing nails?
A: No. Traditional carbide teeth chip because coarse-grain powder leaves microscopic fault lines across large tooth faces. The PG-5 uses sub-micron tungsten carbide powder pressed at high density, creating a uniform structural matrix. Combined with robotic high-frequency tri-metal (Silver-Copper-Silver) brazing, the joint flexes under shock load instead of shearing off the pocket.
Q: How does 48T tooth geometry cut both soft timber and 1.5mm steel studs without burning or dulling?
A: The 48-tooth count provides the exact tooth engagement ratio needed for 165mm blades running between 4,000 and 5,500 RPM. The alternating bevel (BC) teeth score wood fibers cleanly for splinter-free cuts, while the flat chisel teeth rapidly clear steel chips, preventing frictional heat buildup in sheet metal.
Q: What specific battery runtime improvements can field contractors expect on 18V/20V platforms?
A: Because cutting resistance is directly tied to tooth surface area traveling through the kerf, reducing tip dimensions from 5.3×1.7mm to 3.0×1.3mm lowers mechanical drag by ~42%. On typical 5.0Ah brushless cordless saws, field tests show 25% to 30% more linear meters cut per battery pack.
Q: Does cutting sheet steel or conduit produce heavy sparks and rough burrs that require deburring?
A: The blade cuts with a cool, shearing action rather than abrasive grinding. In steel studs up to 1.5mm, it leaves clean, workable edges with minimal discoloration and very low spark ejection, eliminating secondary grinding steps on site.
Q: Can we order custom arbor sizing, private-label laser marking, and customized packaging?
A: Yes. Factory direct OEM/ODM orders support custom laser-etched branding, safety markings, barcode labels, and skin-card or blister packaging starting at an MOQ of 500 units per size. Pre-production testing samples are available for commercial partner qualification.
