Router Bit / Collet Fit 

It is essentially important to know how deep the shank of a router bit should
fit into the collet. Refer to the picture on the right and consider the
following:

• Insert the shank of the router bit at least 80% of its shank length into
  the collet
• When inserting the shank of the router bit into the collet, allow it to
  bottom out inside the collet, then lift it
  ± 3mm and then tighten
  the collet nut. (When bottoming-out, the bit will fall out and possibly
  cause harm)
• Never over-tighten the collet (It might break)
• Regularly clean the collet from any residue
• Consider a collet as a consumable item. Over time wear and tear will
  cause it to fail.
• Remember that in most routers, the collet and the collet nut forms a
  unit. The collet nut has a retainer clip inside and the collet has a lip
  that clicks into this clip inside the collet nut. Thus
  DO NOT [NEVER] insert the
  collet first into the router shaft, then the Collet nut and then the Router
  bit. THIS IS WRONG. First click the collet into its collet nut and then
  insert it into the shaft.

in the following order: (1) insert the

bit.]

THIS IS WRONG. First click the collet into its collet nut and then
insert it into the shaft. Removing the router bit after tightening will be impossible.

safety

Please ensure that you select a router bit with a
shank (shaft) size that will fit your router. If are in doubt, contact us and we
will confirm if it will work for you.

consider safety for your health and the people around you
General safety suggestions: It is advisable to always follow Safety Guides and keep all equipment in a good condition. Never use blunt cutters and blades. These will simply overheat and disintegrate causing harm to people nearby. Eye protection – clean and scratch free Hearing protection – quality earmuffs Dust masks – discard old and dirty masks Switch machines OFF before leaving the workplace. Unplug machines before changing cutters.

specifications

Explaining
the Specifications:

• (d) » The diameter of the shank or shaft. This size
  should be the same as the collet size of your router. Example: a small router
  is mostly supplied with a quarter inch collet that is 6,35 mm inside diameter.
• (B) » The length of the cutting edge of the
  router bit
• Common collet sizes:
  • 1/4′ collet = 6,35mm inside diameter
  • 8mm collet = 8mm inside diameter
  • 12mm collet = 12mm inside diameter
  • 1/2′ collet = 12,7mm inside diameter
  • 
    NOTE that the 12mm and
    the 12,7mm (1/2′) sizing are often misunderstood. 1/4 inch is not 6mm but
    exactly
    6,35mm. A 6mm shank will not fit in a 1/4 in collet. Wrong sizes will either
    break the collet or the bit will fall out.
• TCT = Tungsten Carbide Tipped
• Allways stay in the MAX Speed range of router
