Three Flutes TCT Router Bits For Woodworking Drilling Machine Tools

Need one bit that cuts solid wood, MDF and plywood on the machine you already own? These 1/2 Three Flutes TCT Router Bits cover it: 1/2 in high speed steel shank, tungsten steel head, 6 / 8 / 9 / 10 / 12 mm cutting diameters, 18–40 mm cutting lengths, 25 sizes in the range, three flutes per head. Run 18,000–24,000 r/min at 8–18 m/min, clockwise rotation. Fits engraving machine, table router, edge-banding machine, electric wood milling machine and hanging machine. Other sizes made to order.

Three things keep a router bench slow: a two flute bit fuzzes MDF at the feed the job needs, a thin body breaks at the shank, and one diameter per purchase means a 6 mm groove and a 12 mm rebate cost twice. The 1/2 Three Flutes Straight Bits take all three off the bench.

It is a three flute TCT straight router bit: 1/2 in high speed steel shank, tungsten steel head, cutting diameters 6 / 8 / 9 / 10 / 12 mm, cutting lengths 18–40 mm, 25 listed sizes from 1/2*6*18 to 1/2*12*40.

Three flutes, not two. Each revolution puts three edges past the work instead of two, so chip load per tooth drops by a third at the same feed. Speed runs 18,000–24,000 r/min: a 6 mm head takes 8-10 M at 18,000 and 14 M at 24,000, a 8 mm head 10-12 M and 18 M.

The head is CNC ground and high frequency welded to the body, the bit is designed to rotate clockwise, and every one ships in its own box. Sizes outside the 25 listed are made to order.

What decides whether this bit fits the collet, and how it behaves in the cut.

• 1/2 in shank — a 12.7 mm shank seats in a 1/2 in collet; measure the collet before ordering.
• 25 sizes in one family — cutting diameters 6 / 8 / 9 / 10 / 12 mm, cutting lengths 18–40 mm, from 1/2*6*18 up to 1/2*12*40.
• Three flutes (3Z) — one edge every 120° of rotation, so chip load per tooth is a third lower than a two flute bit.
• Tungsten steel head — a CNC ground TCT edge that keeps its shape in MDF, plywood and multilayer board.
• High speed steel shank — the 1/2 in handle carries the clamp load of the collet without yielding.
• High frequency welded joint — head and body welded, not pressed on, and it holds through 18,000–24,000 r/min.
• Clockwise rotation — designed to run clockwise; the other way loads the edge from behind and twists the shank.
• Published feed chart — 6 mm head: 8-10 M at 18,000, 12 M at 21,000, 14 M at 24,000. 8 mm head: 10-12 M, 14 M, 18 M.
• Individual box — each bit boxed on its own, so the 1/2 in shank and the ground edge arrive unbumped.
• Machine range — engraving machine, electric wood milling machine, edge-banding machine, table router and hanging machine.

On a router bench the choice is usually to keep running a bit that fuzzes, or to stop and hunt for the right diameter. One size range shortens both.

• One range, not five purchases. 6 / 8 / 9 / 10 / 12 mm diameters and 18–40 mm lengths sit in one family, so a groove and a rebate come off a single order.
• One collet, five diameters. the whole range clamps in the same 1/2 in collet, so changing diameter never means changing holder.
• Cleaner MDF edge at the feed you run. three edges per revolution cut chip load by a third against two flutes, which is what stops the fuzz line at 8–18 m/min.
• Fewer broken shanks. a 1/2 in high speed steel handle in a matching collet carries the load instead of the edge.
• Head wear, not body wear. tungsten steel on a CNC ground head, welded at high frequency, so abrasion is spent on the edge that cuts.
• A feed chart you can hand over. six combinations, 8-10 M to 18 M at 18,000–24,000 r/min, turn setup into a lookup.
• Arrives ready to clamp. every bit is boxed on its own, so the 1/2 in shank and the ground edge reach the machine unbumped.
• No dead end on an odd size. customization means a size outside the 25 listed needs no new tooling search.

Yes, as long as the collet is 1/2 in and not worn. The shank is 1/2 in (12.7 mm); a worn or undersized collet will not hold it, and the shank can then vibrate or twist at speed. Measure the collet and replace it with a standard 1/2 in one before running.

1/2 in shank, 6 mm cutting diameter, 20 mm cutting length. Every code in the range follows the same order, so 1/2*8*25 is a 1/2 in shank, 8 mm head and 25 mm cutting length. The range runs from 1/2*6*18 to 1/2*12*40.

Yes. Solid wood board, MDF, plywood board and multilayer board are all listed for this bit. Three flutes split the chip load three ways, which matters most in MDF, where a two flute bit at the same feed tends to leave a fuzzy edge.

Between 18,000 and 24,000 r/min, with feed matched to the head. A 6 mm head takes 8-10 M at 18,000, 12 M at 21,000 and 14 M at 24,000. A 8 mm head takes 10-12 M, 14 M and 18 M at the same three speeds.

Three flutes put an edge past the work every 120° instead of every 180°, so each tooth takes a smaller chip and less heat enters the board. That is the difference between a clean edge and a burnished one in MDF at the same feed rate.

Engraving machine, electric wood milling machine, edge-banding machine, table router and hanging machine are all listed. Fit depends on the collet and the 1/2 in shank, not on the machine plate, so check the collet first.

Yes. Customization is supported, and diameters and cutting lengths outside the 25 listed sizes are produced to order. Send the cutting diameter and cutting length you need, or the code from the bit you are replacing.

Clockwise. The bit is designed to rotate clockwise; running it counter-clockwise loads the edge from the back and can twist the shank. Confirm spindle direction before the first cut, and clamp it in an unworn 1/2 in collet.
