Carbide Engraving Cutter Woodworking Machine Tool Straight Flute Bit 1/8 Inch Shank

Carbide Engraving Cutter from Shunhongyu is a straight-flute V-bit for ultra-fine pattern carving on woodworking machines. It cuts acrylic, PVC, plastic board, hardwood, white wood, and copper. Minimum bore diameter is 1/8 inch, angles are 10°, 20°, or 30°, and overall length runs 30~80mm. Confirm your spindle or collet accepts a 1/8-inch shank and that your work calls for the angle and length you order. The carbide body holds the tip shape through fine detail passes.

When fine lettering or shallow relief starts tearing instead of cutting, the cause is often a tip that cannot hold a sharp point through the pass. A straight-flute V-bit with a conical tip and flat bottom keeps the point engaged in acrylic, PVC, plastic board, hardwood, white wood, and copper.

This is a carbide engraving cutter with a straight flute and a minimum bore diameter of 1/8 inch. Overall length runs 30~80mm, so you can reach different depths without changing the setup. It fits woodworking machines that accept a 1/8-inch shank. Check your collet or spindle bore against that 1/8-inch minimum before ordering, and pick the angle and overall length that match your cut.

Mount it like any straight-shank bit: seat the 1/8-inch shank fully in the collet and tighten. A fully seated shank reduces runout at the tip, which matters when the point is cutting thin lines. The straight flute clears chips from fine pattern carving in plastic and wood.

Supply is straightforward: the cutter comes in the angle and overall length you select, and customisation is not stated. For an enquiry, send the material you are cutting, the angle you need, the overall length, and the shank size your machine takes. That lets the supplier match the cutter to your spindle and your pattern depth without back-and-forth.

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

• Fine line engraving — A conical tip with a flat bottom holds a sharp point for ultra-fine pattern carving in thin-line characters and shallow relief.
• Material range — Cuts acrylic, PVC, plastic board, hardwood, white wood, and copper with the same straight-flute geometry.
• Angle choice — Available in 10°, 20°, and 30° full angles so you can match the point width to the detail you are cutting.
• Shank fit — The 1/8-inch minimum bore diameter fits collets and spindles that accept a 1/8-inch shank.
• Reach options — Overall length from 30~80mm lets you set depth for shallow relief or deeper pattern work.
• Straight flute — The straight flute clears chips from fine pattern carving and keeps the cut line visible.
• Carbide body — Carbide holds the tip shape through repeated fine-detail passes in plastic, wood, and copper.
• Tip wear point — The conical tip is the wear point; check it between jobs when cutting abrasive plastic board or copper.
• Seating the shank — Seat the 1/8-inch shank fully in the collet and tighten to reduce runout at the tip.
• Pattern carving use — Suited to ultra-fine pattern carving where a standard router bit is too large for the detail.

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

• Holds detail in soft plastics. A sharp conical point keeps thin lines clean in acrylic and PVC, so fine text does not smear or tear on the pass.
• One bit family covers several materials. The same cutter handles hardwood, white wood, plastic board, and copper, which cuts the number of setups you keep on the bench.
• Angle options match line weight. Choosing between 10°, 20°, and 30° lets you set the point width for delicate lettering or slightly wider relief without changing machines.
• Length range suits depth changes. Overall length from 30~80mm means you can reach deeper patterns or shallow relief with the same 1/8-inch shank.
• Straight flute keeps the cut clear. Chips exit along the straight flute, so the tip stays visible and the pattern line stays readable during fine carving.
• Carbide tip resists rounding. The carbide body keeps the point sharp through repeated passes, which reduces rework on fine pattern jobs.
• Simple fitment check. Confirm your collet takes a 1/8-inch shank and pick the angle and length; that is the whole fitment decision before ordering.
• It fits the machine you already run. The engraving cutter is made for woodworking machines, so it returns to the same shaft, bracket or spindle without re-machining the mounting.

It cuts acrylic, PVC, plastic board, hardwood, white wood, and copper. The straight-flute carbide tip is intended for ultra-fine pattern carving in those materials, not for heavy stock removal.

Choose 10°, 20°, or 30° based on the line width and detail you need. A sharper angle suits thinner lines, while a wider angle gives a stronger point for slightly broader relief.

It fits machines that accept a 1/8-inch shank. Check your collet or spindle bore against the 1/8-inch minimum bore diameter before ordering.

Overall length runs from 30~80mm. Pick the length that reaches your pattern depth without over-extending the shank in the collet.

Seat the 1/8-inch shank fully in the collet and tighten. A fully seated shank reduces runout at the tip, which matters for fine line work.

Yes, the conical tip and flat bottom are made for ultra-fine pattern and text engraving. The straight flute clears chips so the line stays visible.

Send the material, the angle, the overall length, and your machine's shank size. That lets the supplier match the cutter to your spindle and pattern depth.

Customisation is not stated. The cutter is supplied in the angle and overall length you select, so confirm your requirements in the enquiry.
