Double Edged Straight Groove Pointed Knife For CNC Woodworking Router Bit

Double Edged Straight Groove Pointed Knife for CNC woodworking machines, SKU CUT027. It fits CNC routers cutting hardwood, imported mahogany, hard solid wood, artificial stone and hard bamboo. Alloy body, blade diameters R0.5 and R1.0, full angles 10°, 15°, 20°, shank diameters 6mm and 8mm, total lengths 60/70/80/100mm. The double edge straight groove is built to resist breakage. Confirm your collet accepts 6mm or 8mm shank and your spindle speed suits the full angle. Customisation is supported; send your material, depth and shank size with the enquiry.

Deep relief and three-dimensional carving in hardwood and imported mahogany puts side load on a pointed cutter. A single-flute tool concentrates that load at the tip and the shank, and breakage stops the job. The double edged straight groove spreads cutting stress across two edges, which is why this knife is made difficult to break for deep plunge work in hard solid wood.

The knife is an alloy CNC woodworking pointed cutter with a double edged straight groove. Blade diameters are R0.5 and R1.0; full angles are 10°, 15° and 20°. Shank diameters are 6mm and 8mm, and total lengths are 60/70/80/100mm. It fits CNC woodworking machines.

Check the collet bore and the shank diameter before mounting: a 6mm shank needs a 6mm collet, an 8mm shank needs an 8mm collet. Seat the shank fully and tighten the nut. The straight groove clears chips from deep cuts, and the pointed tip reaches into relief details.

Customisation is supported. Tell the buyer's team the material you cut, the blade diameter R0.5 or R1.0, the full angle 10°, 15° or 20°, the shank diameter 6mm or 8mm and the total length 60/70/80/100mm you need. Send those details with your enquiry, plus a sample of the cut if you have one, so the knife matches your machine and job.

What the specification fixes, and what it leaves to the machine:

• Deep relief carving in hardwood — The double edged straight groove pointed knife is made for deep relief and three-dimensional carving in hardwood, imported mahogany and hard solid wood on CNC woodworking machines.
• Breakage resistance at the tip — Two cutting edges share the load during high-speed operation, which is why this pointed knife is built difficult to break compared with a single-edge tool in dense stock.
• Blade diameter choice — Blade diameters R0.5 and R1.0 let you pick a finer or stronger point for detail work versus deeper cuts in hard solid wood and imported mahogany.
• Full angle options — Full angles of 10°, 15° and 20° cover fine detail through to heavier stock removal, so one knife family suits different carving depths on the same machine.
• Shank fit for CNC collets — Shank diameters of 6mm and 8mm match common CNC collets; check your collet bore before ordering so the knife seats fully and runs true.
• Total length for reach — Total lengths of 60/70/80/100mm let you choose reach for shallow panels or deeper three-dimensional carving without the shank bottoming out in the collet.

What changes on the shop floor when the right part goes back in:

• Fewer stoppages from broken points. With two edges sharing the cut, the knife is difficult to break in hard solid wood and imported mahogany, so deep relief jobs run longer between tool changes.
• One knife family covers several jobs. Blade diameters R0.5 and R1.0, full angles 10°, 15° and 20°, and lengths 60/70/80/100mm let you cover detail and deep carving without stocking unrelated tools.
• Fits your existing CNC collets. Shank diameters of 6mm and 8mm match common CNC collets, so you can mount the knife on your router after a simple collet check, with no adapter.
• Cuts beyond wood. The same pointed knife handles artificial stone and hard bamboo, which means one setup can move from hardwood carving to harder materials without changing tool type.
• Chip clearance in deep cuts. The straight groove clears chips during deep plunge carving, reducing packing at the point and keeping the cut consistent through three-dimensional relief work.
• Reach matched to the job. Total lengths of 60/70/80/100mm let you choose a shorter, stiffer tool for shallow detail or a longer one for deep relief, within the limits of your collet.

Check your collet: the knife comes with 6mm or 8mm shank diameters, so your collet must clamp one of those sizes. Measure the collet bore and confirm the total length 60/70/80/100mm you need before ordering.

It is suitable for hardwood, imported mahogany, hard solid wood and other large relief and deep three-dimensional carving, and it can also carve artificial stone and hard bamboo.

Choose R0.5 for finer detail and R1.0 where you want a stronger point for deeper cuts. Both are available, and the right choice depends on the relief depth and material you are cutting.

Pick from 10°, 15° and 20° according to your carving depth and material. A sharper angle suits fine detail, while a heavier angle suits deeper stock removal in hard solid wood.

The double edged straight groove shares cutting load across two edges during high-speed operation, which is why it is built difficult to break in dense materials like imported mahogany and hard bamboo.

Seat the shank fully in the collet that matches its 6mm or 8mm diameter, then tighten the nut. A fully seated shank runs true and keeps the pointed tip cutting accurately in deep relief work.

Yes, customisation is supported. Send your required blade diameter R0.5 or R1.0, full angle 10°, 15° or 20°, shank diameter 6mm or 8mm, and total length 60/70/80/100mm with your enquiry.

Send the material you cut, the blade diameter, full angle, shank diameter and total length you need, plus your machine collet size. That lets the knife be matched to your CNC setup and job.
