{"product_id":"sparkfun-mc-etcher-diamond-drag-bit-120-degree","title":"SparkFun MC Etcher - Diamond Drag Bit (120 Degree)","description":"\u003cp\u003eMC Etcher is a diamond drag bit. It is perfect for fine line engraving on composites, metals, and glass. MC Etcher drags a diamond-coated, spring-loaded tip over the surface of your material to create an etched or engraved pattern, it does not cut with flutes like a normal endmill.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e The drag engravers are not meant to rotate so the spindle needs to be turned off when using MC Etcher.\u003c\/p\u003e \u003cp\u003eShips in a reusable storage tube.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003e90 Degree or 120 degree tip?\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThe 90-degree tip has better penetration in very hard or anodized materials.\u003c\/p\u003e \u003cp\u003eThe 120 deg tip provides slightly wider lines in softer materials such as fiberboard but has less penetration in harder materials.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eRecommended Diamond Drag Bit Speeds and Feeds\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eWe've tried the MC Etcher with a variety of materials and we don't find a lot of difference between the speeds and feeds that work for each material.

For instance, softer materials, like plastics, cause very little wear while harder materials, like glass and stone, can cause much higher wear.\u003c\/p\u003e \u003cp\u003eIf you are using MC Etcher to engrave hard materials, it's worth doing a test to find the minimum toolpath density (or the maximum stepover) that will give you the look that you're trying to achieve.
