COVE ROUTER BIT 3/8'
This
is an affordable router bit range that is well supported throughout South Africa. All
our Tork Craft router bits are Tungsten tipped. Tork Craft is a well-known BRAND
in most retail stores.
At a glance:
¼" Ø Shank router bit with a 9,5 mm (3/8 inch) radius to profile a cove shape in wood.
Application:
This router bit is used with a plunge router to profile the edge of wood to produce a concave edge that has a 9,5 mm (3/8 inch) radius. The 6.35 mm shank should fit most small routers.
Definition: Cove Router Bits combine one or more concave radii (cove) to
form many unique edge profiles. These profiles may also be known as 'fluted' router bits. A trim bit on which one edge
has a curved radius.
Coves are used by professional installers to bridge the gap between the bottom of the wall and the
floor. A cove may also be used to form an inside corner. It may also be applied as a decorative profile.
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.
| Shank dia. (d) | Radius (R) | Cutting Length (B) |
| 6,35 mm (1/4") | 9,5 mm (3/8 inch) | 28,6 mm (1 1/8 inch) |
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 bit
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.
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]
in the following order: (1) insert the
collet first into the router shaft, (2)then the Collet nut and (3) then the Router
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.
