Astro Pneumatic Ast1721 8mm Drill Bit For 1756 Spot Weld Drill

The Astro 1721 8mm Drill Bit for Spot Welds is receiving mixed reviews from customers who have utilized it for automotive applications, especially in projects involving the removal of spot welds. Many users have praised its effectiveness in cutting through factory spot welds, making it a valuable tool for tasks such as replacing floor pans in vehicles. For instance, one reviewer mentioned its success in aiding with a '70 Nova, while another noted its efficiency in removing old floor pans from a Jeep. However, there are several drawbacks that potential buyers should be aware of. One common concern is the durability of the bit. Many customers reported that the wear life of the drill bit is limited, often becoming dull after just a handful of spot welds. One reviewer specifically noted that they only managed to get 6-7 spot welds out of it before it started to lose effectiveness. Additionally, the shorter length of the bit presents challenges when working in tight spaces, limiting its functionality in deeper areas. Some users have also encountered quality issues, such as flat spots that prevent the bit from fitting properly into drill chucks, which can hinder performance. The cutting precision was another area of concern, with reports of the bits not delivering clean cuts. One body technician expressed dissatisfaction by comparing the Astro bit unfavorably to a traditional mini-hole-saw style spot weld cutter. In summary, while the Astro 1721 Drill Bit offers decent performance for certain applications, frustrations surrounding its limited durability and quality control may lead some users to seek alternative solutions. **
