Replacement Diamond tip assembly for the 3/8" engraving tool
60 deg sharpest point: best for harder materials
90 deg general point: great for most materials
120 Less sharp: wider engraving line in softer materials
Note on tips. The 60 degree tip has the best penetration in very hard or anodized materials. The 90 deg works well for most applications and the 120 deg tip provides slightly wider lines in softer materials such as fiber board but has less penetration in harder materials.
optional heavy tension spring for 3/8" tool
This is a optional heavy tension spring. The stock spring works well for most cases but if you need more pressure for a deeper cut or harder materials this heavy spring is available. ( caution using to much tension as tip or tool could be damaged)
