How hard is the cutting material?

The carbide grade used in this slottingsaw small clamp handle delivers 7,000–9,000 HV / 1,500–2,000 HV hardness, which keeps the cutting edge sharp under continuous load.

Can you supply OEM or ODM parts, and how fast?

Yes. VPOINT TOOLS runs two factories in China (Chengdu and Dongguan) and accepts OEM and ODM orders. Standard samples and in-stock items ship within 24-48 hours; custom tooling is quoted per specification.

Which machines and materials is this slottingsaw small clamp handle used for?

It is used on CNC routers, table saws and spindle moulders for cutting particle board, MDF, plywood, solid wood and aluminium composite panels. Chipbreaker or replaceable-insert models are available for high-volume production runs.

Do you ship worldwide?

Yes. VPOINT TOOLS ships carbide and PCD woodworking tooling to more than 100 countries. Tell us the destination and application and we will confirm freight cost and lead time.

Slottingsaw Small Clamp Handle

Small clamp handles for slotting saws, D 20 and 22 mm, length 45.6-60.5 mm. Secure saw mounting for slot and groove cutting on woodworking machinery.

The VPOINT Slottingsaw Small Clamp Handle is a carbide-tipped circular saw blade. Ideal for slot cutting on woodworking machinery, groove and trench machining and panel slotting operations.

Product Description

The small clamp handle for slotting saws holds the saw blade in the machine spindle for slot and groove cutting, in 20 and 22 mm clamp diameters with overall lengths as listed in the specifications table.

Design and Construction

The small clamp handle for slotting saws holds the saw blade in the machine spindle for slot and groove cutting. Clamp diameters (D) are 20 and 22 mm with overall lengths (L) of 45.6 to 60.5 mm, covering the common small slotting saw bore sizes used on woodworking machinery. The handle section gives the operator a firm grip for manual blade changes without tools.

How It Works

The slotting saw seats in the clamp bore and is secured by the handle; the clamped saw then cuts slots and grooves as the workpiece feeds past. Matching the clamp diameter (D) to the saw bore and the length (L) to the machine mounting keeps the saw concentric and the slot width constant.

Applications

Slot cutting on woodworking machinery
Groove and trench machining
Panel slotting operations
Saw blade mounting and changeover

Suitable Materials

Solid wood
Veneered plywood
MDF and engineered wood
Laminate-faced components

The steel body keeps its mounting reference across blade changes, keeping slot width and depth stable across production runs.

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 clamp handle. Order by part number with the diameter and length stated in the specifications table below.

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.

Frequently Asked Questions

What is the Slottingsaw Small Clamp Handle used for?

The small clamp handle for slotting saws holds the saw blade in the machine spindle for slot and groove cutting.

How do I choose the right size?

Refer to the specification table on this page: part numbers fix the cutting diameter, shank and cutting length. State the diameter, shank and cutting length you need when ordering.

Which materials does it suit?

Typical materials include Solid wood, Veneered plywood, MDF and engineered wood. Confirm the material grade and machining conditions for the specific tool before ordering.

Can I order a custom version?

Yes. Send the profile drawing or item code together with the workpiece material, machine model, cutting direction and quantity. Tools are produced to order, and each tool is packed in an individual plastic box.
