  8. Engraving and Etching: Engraving and etching bits are used for creating detailed designs and inscriptions on materials like metal, glass, and wood. They allow for precise control and customization.

  9. Polishing and Finishing: Some rotary tool bits are designed for polishing and finishing tasks. They can be used to give a glossy finish to metals, plastics, or stones.

  10. Maintenance: Proper maintenance of rotary tool bits involves keeping them clean and free from debris, ensuring they are properly attached to the tool, and replacing them when they become dull or worn out. Dull bits can be less effective and may cause excessive heat buildup.

When working with rotary tool bits, it's essential to follow the manufacturer's guidelines and safety recommendations to prevent accidents and ensure efficient and precise results.

User questions & answers

Question: Anyone know if these will fit a Dremel Moto-tool
Answer: I don't know about shotgun barrels. I'm using them on knife blades. Should be about the same. I just take my time and don't rush.
Question: are these 3sets of the same bits
Answer: Although I can not give you a definative answer, my guess would be yes, but need to keep water on the drilling area. Go slow. I engrave on glass as a hobby and never encountered any problems going deep , BUT...glass and porcelain are different of course. GO SLOW...VERY SLOW, WITH VERY LITTLE PRESSURE ON THE BIT. USE PLENTY OF WATER. HOPE THIS HELPS YOU. GOOD LUCK.
Question: How effective are these on shotgun barrel
Answer: Hi! The HC2069 is compatible with tools that accept SDS-plus bits. We recommend getting in touch with the manufacturer of Bauer to confirm the compatibility. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.
Question: Can I use this to drill a small hole in the bottom of a porcelain teacup without cracking

User questions & answers

Question: What is the rpm rating on these? Above 54,000 rpm
Answer: Yes. I have used these bits in my Dremel 4000.
Question: Can this be used for a dremel
Answer: These bits will work for aluminum provided the engagement force is light. To much force and the grinding heads will dull. For smoothing and polishing you find the best results with an abrasive wheel set. They are also available online.
Question: Good for aluminum? I want to Port & Polish my aluminum cylinder heads
Answer: I do Metal Fab and use pneumatic die grinders daily, I bought these to uses with a "pencil grinder" ( die grinder with 1/8 shank) mostly for bronze which is relatively soft. I have used them on steel and they will work but the lifetime of the burr will likely be short. More than anything I found that these burs are not well balanced and at higher rpms they deflect enough to cause vibration and sometimes enough to make using them unsafe- But they are cheap
Question: Any experience using these to grind steel? I need to enlarge a framework hole to let radiator drain better. Drilling is not an option
Answer: These carbide burrs, we recommend The cutting speed:5000-20000 rpm/min,and hardness of materail ususlly under HRA65.
