## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent product
*by R***S on May 22, 2024*

I used this product to engrave patterns into an ultra compact material (Lapitec) with a cnc. I had my doubts but it performed well above my expectations at 4800 rpm, 1/32” depth, 1”/minute travel with plenty of water for coolant. Engraved 50 stars in an American flag roughly 19”x 10” with just one bit and it still looks new. Kudos

### ⭐⭐⭐⭐ Excelente herramienta.
*by J***. on October 18, 2019*

Excelente herramienta de grabado para mármol en CNC...!!!Saludos. Dios les bendiga.

### ⭐⭐⭐⭐⭐ Buy more than you think
*by J***S on February 23, 2023*

The very fine point will wear down quickly. I was engraving granite and found that 1/16 depth was about the max I could go in one pass without destroying the tip. Use lost of water for cooling. I used them on CNC machine 10 ipm feed rate and 10,000 rpm. The shank is not 1/4", but will work fine if you have ER collets that adjust to range of sizes.
