Double Head Hard Wood Cutting Knife Coating Long Spiral Router Bit for Solid Wood

Product Description

Need one bit for curved bending, thick solid-wood sheet and shaped profiles, without a tool change in the middle of the job? This double-head long spiral router bit covers all three. Blades come in 4, 5, 6 and 8 mm, each on a shank of the same 4, 5, 6 or 8 mm, overall length runs 120, 150, 165, 200 and 230 mm, and the two SKUs split by coating: CUT030 uncoated, CUT031 coated. Alloy cutting heads, rubber wood through beech, customization supported.

Woodshops cutting solid wood run into the same three problems: a different bit for the curved bend, the thick panel and the shaped profile; a tool change mid-job that leaves the spindle idle; and a chipped exit edge that has to be sanded back before the part leaves the bench. The double-head long spiral router bit removes all three, because two cutting heads share one shank and one setup.

It is a two-head spiral cutter for new-generation solid wood cutting machines. A single straight edge meets the wood once per revolution; this tool carries two heads along a long spiral flute, so one head cuts while the other keeps the feed continuous. Blade diameters are 4, 5, 6 and 8 mm, each on a shank of the same size, so a 6 mm head runs straight into a 6 mm collet without an adaptor sleeve.

Overall length comes in five steps: 120, 150, 165, 200 and 230 mm, which covers light profile trimming and deep super-thick panel molding on one machine. The cutting heads are alloy; the coated version adds a wear-resistant layer that lowers friction and keeps the edge cooler through continuous high-speed passes, while the uncoated version holds its sharpness at a lower cost for standard processing.

Applications: curved bending, super-thick sheet molding and precision shaping in rubber wood, walnut wood, ugin wood, oak and beech.

Product Features

What separates this bit from a single-edge straight cutter:

• Double cutting heads — two edges share one shank, so every revolution cuts twice and the spindle never waits for a second pass.
• Long spiral flute — the edge shears the wood instead of striking it square, which is what keeps the exit edge clean on solid stock.
• Four head sizes — 4, 5, 6 and 8 mm blades on 4, 5, 6 and 8 mm shanks, matched one to one, with no sleeve between head and collet.
• Five overall lengths — 120, 150, 165, 200 and 230 mm, from light profile trimming to deep panel work.
• Alloy heads — alloy edges hold their shape through the interrupted cuts that solid wood produces.
• Coated or uncoated — CUT031 carries a wear-resistant coating that cuts friction and heat; CUT030 runs uncoated at a lower cost.
• Five species listed — rubber wood, walnut wood, ugin wood, oak and beech are all named for this bit.
• Built for new-generation machines — the shank is dimensioned for current solid wood cutting spindles.
• Three jobs, one tool — curved bending, super-thick sheet molding and precision shaping.
• Customization supported — diameter, length and coating can be specified to the job.

Product Advantages

The choice is usually between sending shaped parts out and running them in-house on a single-edge bit that needs a change halfway through the job. This bit closes that gap.

• One setup per job. A single double-head bit covers the curved bend, the thick panel and the profile, so a run that took three tool changes now takes one.
• Chip-free exits mean less bench work. The spiral flute shears the grain instead of lifting it, so the sanding pass after the cut gets shorter.
• The coated SKU pays off on long runs. CUT031 carries a wear-resistant layer that lowers friction and holds the edge through continuous high-speed passes.
• A size for every spindle. 4, 5, 6 and 8 mm heads on the same 4, 5, 6 and 8 mm shanks, and 120–230 mm of length, so no adaptor and no second tool holder is needed.
• One tool family for five species. Rubber wood, walnut wood, ugin wood, oak and beech run on the same bit, so a stock change is not a re-tooling job.
• Custom work is normal, not special. Diameter, length and coating can be specified, so the bit fits the spindle you already own.

Frequently Asked Questions

What is the difference between CUT030 and CUT031?

The coating. CUT031 is the coated SKU: a wear-resistant layer that lowers friction and heat and holds the edge through continuous high-speed cutting. CUT030 is uncoated, keeps full sharpness and costs less for standard processing.

Will a 6 mm blade fit my 6 mm collet?

Yes. Blade diameter and shank diameter are matched one to one, so the 4, 5, 6 and 8 mm heads each run on the same size shank, with no adaptor sleeve.

How long a bit do I need to order?

Pick the shortest length that clears your part. Overall length comes in 120, 150, 165, 200 and 230 mm: the short end suits profile trimming, the long end suits deep super-thick panel molding.

Does it chip the exit edge in oak and beech?

No. The long spiral flute shears the grain instead of lifting it, and that is what keeps the cut clean on dense stock such as oak and beech.

Can one bit handle curved bending and thick panels?

Yes. The double-head design is listed for curved bending, super-thick sheet molding and precision shaping, so one tool family covers all three operations.

Is it for older machines or current ones?

Current ones. It is built for new-generation solid wood cutting machines; send your spindle size and the matching blade and shank diameter is confirmed before the order.

Can you make a custom diameter or length?

Yes. Customization is supported — blade diameter, shank diameter, overall length and coating can all be specified, including sizes outside the four standard heads.

What does it cost and how do I order?

Quotation on request. Send the SKU, the blade diameter and the overall length, and the quote comes back for that exact combination with lead time and packing.
