Palton PCD Bottom Cleaning Bit — Flat Floors, Zero Rework
The Problem It Solves
Most shops accept a certain amount of hand work after CNC routing. A rough pocket floor here, resin smear on melamine there, a few thou of residual stock that the finisher sands off later.
Multiply that across hundreds of sheets a month and it's real money.
This tool is built to delete that step.
How It Works
Unlike standard end mills that engage with the corner radius or sharp tip, this straight-bottom PCD bit presents a flat diamond cutting face to the workpiece. The entire tool diameter contacts the material surface simultaneously — cleaning, flattening, and finishing the slot or pocket base in a single lateral pass. No radial tool marks. No scalloped floor. No material left behind.
Where Operators Deploy It
Nesting-based cabinet production: Clearing islands and bridges left between routed parts on MDF and HPL sheets
Melamine & laminate panels: Removing the top skin cleanly without chipping or peeling the decorative layer
**Aluminum composite panels
(ACP):** Surfacing and flattening before fine routing or drilling
• Solid surface & compact laminate: Dressing edges and cleaning recessed features
• Post-roughing cleanup: Square-shoulder floor finishing after bulk material removal

What Makes the PCD Edge Different
Here
Bottom cleaning is a worst-case wear scenario: large contact area, continuous engagement, high abrasive load from panel fillers and binders. Carbide edges round over quickly under these conditions — once the sharp corner is gone, the tool burnishes instead of cuts. Resin heats up, smears, and bakes onto the tool face.
Diamond doesn't have this problem. The PCD cutting edge maintains its geometry through abrasive panel stock, shedding chips rather than collecting them. Heat moves into the chip stream, not the tool body. The result is a genuinely flat floor on the thousandth sheet, not just the first.
Real Shop-Floor Outcomes
Downstream sanding eliminated on pocket and slot floors
Vacuum hold-down improved because sheet backs sit truly flat on the table

• Diameter holds tolerance longer, meaning pocket dimensions stay consistent batch to batch
• No resin buildup on the cutting edge during extended runs on coated or impregnated panels
Palton PCD Straight Bottom Cleaning Cutter is a dedicated flat-bottom CNC milling tool, designed to solve uneven slot bottom, residual leftover material and rough shoulder surface problems in panel furniture and non-ferrous metal machining
Adopt high-density HPHT sintered PCD composite blank + high-rigidity integral tungsten carbide shank, vacuum metallurgical brazing process ensures tight combination between diamond tip and shank, anti-falling under heavy cutting load.
Main flute types available in stock: 1-flute & 2-flute; standard shank sizes 6/8/10/12mm. Cutting diameter, cutting depth, overall length can all be customized by customer drawings, perfectly compatible with CNC nesting machine, engraving machine, machining center and panel cutting equipment
2. Core Competitive Advantages
Special Flat-Bottom Cutting Geometry
Horizontal flat PCD cutting edge ensures full contact with slot base, completely clear residual scraps and level uneven bottoms in one pass, forming smooth flat square shoulders without secondary sanding.
Ultra-Wear Resistant PCD Diamond Material
PCD hardness up to 8000HV, service life 8–10 times longer than ordinary carbide cutters, drastically reduce frequent tool replacement and production downtime for automatic production lines.
Laser Ultra-Fine Ground Sharp Edge
Precision laser edge grinding eliminates micro-chipping, low-friction anti-buildup cutting surface; no board bursting, aluminum sticking or burrs after processing, directly get mirror-smooth flat finish.
Stable Vacuum Brazing Structure
Vacuum welding removes air impurities inside the bonding layer, achieves metallurgical fusion of PCD and carbide shank, supports multiple regrind cycles to lower long-term tool procurement cost.
Excellent Thermal Conductivity
Diamond material dissipates cutting heat rapidly, withstands long-term high-speed continuous machining without edge burning, stable dimensional accuracy for 24h batch production.
Strict Batch Dimensional Consistency
All cutters are inspected under high magnification microscope, dimensional tolerance controlled within ±0.005mm, uniform cutting performance for mass automatic processing.
