Detachable Chamfering Knife

Detachable chamfering knives, D 27 and 35 mm, insert radii 2-4.8 mm, shank 6.35 or 12.7 mm, adjustable height 10-38 mm. One-pass edge chamfering on panel lines.

The VPOINT Detachable Chamfering Knife is a chamfering router bit with insert knives. Ideal for edge chamfering on panel lines, edgebander pre-milling and edge deburring and cleanup.

The detachable chamfering knife is a replaceable-insert cutter on a 40Cr chrome-molybdenum steel body; the angled insert cuts the chamfer and can be exchanged for a different radius. Cutting diameters and insert sizes follow the specifications table.

Design and Construction

The detachable chamfering knife is a replaceable-insert cutter on a 40Cr chrome-molybdenum steel body. The angled insert cuts the chamfer and can be exchanged for a different radius. Cutting diameters (D) are 27 and 35 mm with shanks (d) of 6.35 or 12.7 mm, insert radii (R) of 2, 3 and 4.8 mm, and adjustable cutting height ranges (H) from 10-30 mm to 18-38 mm.

How It Works

The angled insert shears the chamfer along the panel edge in one pass. Because the insert is detachable, the same body covers different chamfer radii and panel thicknesses — swap the insert instead of changing the tool. The height range covers the common panel thicknesses on edgebander pre-milling stations.

Applications

  • Edge chamfering on panel lines
  • Edgebander pre-milling
  • Edge deburring and cleanup
  • Laminate edge preparation

Suitable Materials

  • Melamine-faced particleboard and MDF
  • Laminate (HPL) sheets
  • Veneered plywood
  • Solid wood

Suitable materials: melamine-faced particleboard, MDF, laminate HPL, veneered plywood, solid hardwood

The steel body keeps its mounting reference across insert changes, keeping chamfer position stable across long production runs.

System Comparison: Replaceable Insert vs. Solid Knife

Insert-system knives keep the expensive part — the body — in service and replace only the cutting edge. For production cutterheads running repeat profiles, this is usually the lower-cost way to hold edge quality.

Property Replaceable Insert Knife (This Tool) Solid Profile Knife
Edge replacement Swap the worn insert only; the steel body stays in service Regrind or replace the complete tool
Body material 40Cr chrome-molybdenum steel body, reused across insert changes Whole tool consumed as the edge wears
Downtime per edge change Minutes — index or swap the insert Send out for regrinding or buy a new tool
Profile changes Fit a different insert geometry to the same body New tool required per profile
Edge condition Fresh edge on every change; consistent cut quality Edge quality drifts between regrinds
Best suited for Production cutterheads with repeat profiles One-off profiles and low-volume work

Solid knives remain the better choice for one-off profiles and very low volumes.

Material Comparison: PCD vs. Tungsten Carbide

The figures below are typical industry data for production woodworking. PCD does not replace carbide in every job — carbide remains the right choice for low-volume general work — but on abrasive sheet goods the difference in blade life is decisive.

Property PCD Diamond (This Blade) Tungsten Carbide
Hardness 7,000–9,000 HV 1,500–2,000 HV
Tool life on MDF / particleboard / melamine 15–20× longer (500–1,200 h) 30–60 h (baseline)
Tool life on solid hardwood 10–13× longer (800–2,000 h) 80–150 h (baseline)
Tool life on abrasive boards (fibre cement / composites) 10–15× longer baseline
Edge renewal Limited regrinds — the economics come from 15–20× longer intervals between changes, not regrind count 4–6 regrinds at shorter intervals
Cut finish Ra ≤ 0.2 μm achievable, stable over the blade life Ra ~0.8 μm typical, degrades as teeth wear
Thermal conductivity 540–560 W/m·K — heat leaves the tooth tip fast ~80 W/m·K
Friction coefficient ≈ 0.05 — lower cutting forces and heat ≈ 0.3
Suited for Abrasive engineered wood, laminates, composites, fibre cement, non-ferrous metals General-purpose solid-wood work; the economic choice at lower volumes

Figures are typical published values; actual blade life depends on the workpiece material, feed rate, depth of cut, machine condition and maintenance schedule.

Delivery Scope

Single knife. Order by part number with the diameter, radius and height range stated in the specifications table below. Replacement inserts are available separately.

Why Choose VPOINT

  • One-year warranty on every cutter — defects in material or workmanship are covered for 12 months from delivery.
  • Custom tooling — geometries, diameters, cutting lengths and shank configurations built to your drawing or sample.
  • Non-standard fabrication — profiles and sizes outside the standard catalogue, including profile restoration and special applications.
  • Resharpening service — cutters return to service after regrinding, restoring near-original edge performance at a fraction of new-tool cost.
  • Factory-direct since 2008 — ISO 9001 manufacturing in Sichuan and Dongguan, China; 40Cr chrome-molybdenum steel bodies; no trading intermediaries.

Send a drawing, a sample or a worn tool, and our engineering team will quote the exact specification you need.

Precision & Quality Control

Every cutter is inspected at micron level before shipment. Cutting edge condition, cutting diameter (ØD), shank diameter (Ød), cutting length (L1) and overall length (L) are measured against the values listed in the specifications table, and cutting edge runout and concentricity are verified on the assembled tool.

Tools measuring outside tolerance are reground or scrapped — they do not ship. Inspection is performed under our ISO 9001 quality system, with batch records retained for traceability.
