Stave Milling Cutters (Concave-Convex Profile) 22 / 30 / 42 / 46 mm – HSS M2

Professional milling cutter set for making staves for hot tubs, tubs, saunas, barrels, rounded furniture, or solid wood boats (kayaks, canoes). The concave-convex profile is precisely calculated to ensure each stave perfectly interlocks with the next, eliminating gaps and leaks. Available in 4 thickness variants – 22, 30, 42, or 46 mm – to perfectly suit your project.

🛠️ WHY CHOOSE THIS SET:

Perfect Sealing: the concave-convex profile is precisely calculated so that each stave fits perfectly with its neighbor, eliminating gaps and leaks.
Durable Premium HSS M2: high-speed steel cutting edges resist intense wear and provide deep, clean cuts without burning the wood fiber.
Full Range of Thicknesses: 22, 30, 42, and 46 mm cover most projects, from curved furniture to large tubs and hot tubs.
Double Machine Compatibility: can be mounted on both spindle moulders (single head) and 4-sided machines, for flexible integration into your workshop.
Long-Term Investment: the inserts can be successively resharpened at a specialized center, and in case of advanced wear, the cutter body can be re-brazed with new inserts.

🔧 Recommended for: tubs and hot tubs for saunas/spas, sturdy barrels, curved furniture, as well as wooden boats (kayaks, canoes).

⚠️ USAGE LIMITATIONS:

Exclusive Purpose: this range is made exclusively from HSS M2 and is intended for processing natural solid wood (softwoods such as spruce, fir, pine, but also hardwoods).
Not Recommended for Composites: ❌ NOT recommended for use on chipboard, MDF, HDF, or other wood-based panels with abrasive adhesive. The synthetic binder prematurely wears out the high-speed steel cutting edge.
This range is not available in T.C.T. (Tungsten Carbide Tipped) variant. For applications on composite materials, please contact us to check the availability of other solutions.

📊 COMPATIBILITY LEVEL BY MATERIAL TYPE (HSS M2)

Softwood (Spruce, Fir, Pine) 100%

Excellent: deep and clean cut, no burning on the fiber.

Hardwood (Beech, Oak, Ash) 75%

Good: solid results, but the cutting edge wears out faster than on softwoods.

Chipboard / MDF / HDF / Laminate Not Recommended

The synthetic binder in these materials prematurely wears out the HSS cutting edge.

🦺 SAFETY MEASURES IN USE:

Mandatory protective equipment: safety glasses (against flying chips), mask or respirator (fine wood dust), and ear protection for prolonged work.
Beware of hands and fingers: maintain a safe distance from the cutting area and use push devices where possible; do not manually intervene near moving cutters.
Check the correct pair: before starting production, ensure that the convex and concave profile cutters correspond to the same thickness variant, for a tight stave joint.
Check the fastening of the cutters on the spindle (including any reduction bushings) before starting the machine.
Observe the recommended RPM of 9,000 RPM, to avoid vibrations or the risk of cutting edge breakage.
