2. Burr (cutter) - Wikipedia

   en.wikipedia.org/wiki/Burr_(cutter)

   These are often used in CNC machining centers for removing burrs (the small flakes of metal) after a machining process. To achieve optimal surface speed and cutting conditions, burrs are rapidly rotated at high speeds, often in the range of thousands or tens of thousands of RPM , which is typically the maximum speed supported by a given spindle.

3. Tipped tool - Wikipedia

   en.wikipedia.org/wiki/Tipped_tool

   Common materials for the cutters (brazed tips or clamped inserts) include cemented carbide, polycrystalline diamond, and cubic boron nitride. [1] Tools that are commonly tipped include milling cutters (such as end mills, face mills, and fly cutters), tool bits, router bits, and saw blades (especially the metal-cutting ones).

4. CNC router - Wikipedia

   en.wikipedia.org/wiki/CNC_router

   A stone CNC router is a type of CNC router machine designed for marble, granite, artificial stone, tombstone, ceramic tiles, glass machining, polishing for arts and crafts, etc. Wood, metal and stone require different "bits" or "inserts". There is bit call as diamond tools with different diameter 4mm, 6mm, 8mm mainly used.

5. Router (woodworking) - Wikipedia

   en.wikipedia.org/wiki/Router_(woodworking)

   Two typical router bits: (top) a 1 ⁄ 4-inch shaft Roman Ogee with bearing, (bottom) 1 ⁄ 4-inch shaft dovetail bit. Router bits come in a large variety of designs to create either decorative effects or joinery aids. Generally, they are classified as either high-speed steel (HSS) or carbide-tipped, however some recent innovations such as ...

6. Tool bit - Wikipedia

   en.wikipedia.org/wiki/Tool_bit

   Originally, all tool bits were made of high carbon tool steels with the appropriate hardening and tempering.Since the introductions of high-speed steel (HSS) (early years of the 20th century), sintered carbide (1930s), ceramic and diamond cutters, those materials have gradually replaced the earlier kinds of tool steel in almost all cutting applications.

7. Speeds and feeds - Wikipedia

   en.wikipedia.org/wiki/Speeds_and_feeds

   While these speeds are fine for small router bits, using larger bits, say more than 1-inch (25 mm) or 25 millimeters in diameter, can be dangerous and can lead to chatter. Larger routers now have variable speeds and larger bits require slower speed. Drilling wood generally uses higher spindle speeds than metal, and the speed is not as critical ...
