LAMBOSS Three Flutes Woodworking Machine Tool TCT Straight Bits Router 8x20

When a straight bit loads up with chips, the cut slows and the edge heats. Three flutes on the 8*20 bit move chips out faster than a two-flute design, so you spend less time clearing the cut and more time feeding stock. The 20mm blade length sets the maximum depth per pass.

This is a TCT straight bit with a 1/2" shank, an 8mm blade diameter, and a 20mm blade length. It fits woodworking machines that accept a 1/2" collet or spindle. To confirm fit, measure your machine's collet opening and compare it to the 1/2" shank, then check that the 8mm diameter and 20mm length match the cut you need.

Mount the bit by inserting the 1/2" shank into the collet and tightening to the machine's spec. Check that the flutes clear the workpiece and that the 20mm blade length covers your cut depth. A secure 1/2" shank keeps the bit from slipping, so the three flutes cut a straight wall without deflection.

Customization is supported. Tell the supplier your shank size, blade diameter, and blade length when enquiring, along with the material you cut and the depth per pass. Confirm how the bits are packed and how many you need. Send the 8x20 reference and any drawing or sample you have.

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

• Chip clearance — Three flutes on the 8*20 bit lift chips out of the cut, so the kerf stays clear and the feed stays steady.
• Shank fit — A 1/2" shank seats in any collet or spindle that takes 1/2" tooling, so you can check fit before you buy.
• Cut width — The 8mm blade diameter sets a fixed 8mm straight cut for grooving, rebating, or joint work on woodworking machines.
• Depth per pass — With a 20mm blade length, each pass can cut up to 20mm deep, which sets your pass count on the job.
• Heat at the edge — Three flutes spread the cut across more edges, which lowers friction and heat buildup at the cutting edge.
• Mounting check — Insert the 1/2" shank fully into the collet and tighten; a seated shank stops slip and keeps the cut straight.
• Wear point — The tungsten carbide tip holds the cutting edge on the 8*20 bit, so the 8mm diameter stays on size through the run.
• Machine compatibility — The bit fits woodworking machines with a 1/2" collet; confirm your machine's collet size and spindle before ordering.

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

• Fewer chip stalls. Three flutes clear chips from the 8mm cut as the bit turns, so the machine keeps feeding instead of stopping to clear a packed kerf.
• Depth set by the blade. The 20mm blade length caps each pass at 20mm, which lets you plan pass count and feed rate before the job starts.
• Fit checked before the cut. A 1/2" shank matches machines that take 1/2" tooling, so you confirm the collet size and avoid a wrong-size order.
• Less heat at the edge. Spreading the cut over three flutes reduces friction on the 8*20 bit, which keeps the carbide edge working through long runs.
• Fixed 8mm width. The 8mm blade diameter cuts a constant groove width, so slots for joints and recesses come out the same size pass after pass.
• Straight walls from a seated shank. Tightening the 1/2" shank in the collet stops slip, so the 8mm cut runs true and the wall stays vertical.
• Sized to your machine. Customization is supported, so you can order the 8*20 bit or specify other dimensions and send your collet size with the enquiry.

Check your router's collet size. The bit has a 1/2" shank, so it fits machines that accept 1/2" tooling. If your router takes a different collet, it will not seat.

It cuts an 8mm wide straight groove. The blade diameter is 8mm and the blade length is 20mm, so each pass can cut up to 20mm deep.

Three flutes clear chips faster and spread the cut over more edges. On the 8*20 bit this means less chip packing and lower heat at the cutting edge.

The 20mm blade length sets the maximum depth per pass at 20mm. For deeper work, take more than one pass and keep the shank fully seated.

The bit is TCT, tungsten carbide tipped. The carbide edge holds the 8mm cutting diameter through the run on woodworking machines.

Customization is supported. Send the shank size, blade diameter, and blade length you need, plus the material and depth per pass, and the supplier can quote.

A 1/2" shank seated fully in the collet and tightened to the machine's spec holds the bit. Check the collet for wear and seat the shank before each run.

Send the 8x20 reference, your machine's collet size, the material you cut, and the depth per pass. Also state the quantity and any drawing or sample you have.
