Features and Benefits
UNCOATED
UNCOATED is as it states no coating. This tool still has many benefits over a coated tool. All coating put heat in the tool causing them to become more brittle. Long reach small diameter tools many times perform better uncoated as they dont snap as easily. Applications were coatings may leave partials in the part. J polished tools coatings tend not to adhere to showing very little benefit in tool life. Micro tooling where surface footage is never going to be achieved. Cost is not much different today but there is still a small up charge for coating.
Benefits of Carbide
Carbide is the most versatile material for cutting all materials. This should be the first choice for rigid cutting. Carbide comes in many different varieties of toughness and hardness. Round tools are limited in varsity as they are extruded. Inserts come in hundreds of combinations as they are sintered and pressed.
When to use Variable Helix
Variable Helix is becoming the standard for all milling tools. It is used to dampen vibration as the flutes enter and exit the material. Depending on the type of variables these tools work great for long reach, slotting, and roughing. Down fall is variable tools like high helix tools can pull out of shrink fit, collets and milling chucks. Weldon flat when roughing is preferred and most failures are chipping from pulling out of work holding
