STROTON Editorial Review

The Stroton HSS Cobalt M35 Spiral Grooved Drill Bit Set seems to be a hit or miss product. While some customers have found these bits to be a game changer as they are able to drill faster, straighter and cooler, others have found the bits to be brittle and easily breakable, resulting in them not being happy with the product at all. The product comes in a plastic case and has average length bits. Although the packaging of the product is not sturdy, the seller is able to deliver in a quick and effective manner. However, there have been complaints from customers about broken bits and packaging issues. Overall, this product seems to work well for some customers while others have faced issues with the quality. It is important to note that these bits are made to drill through hard steel and may not work well with titanium alloys.

Pros

Able to drill faster, straighter and cooler
Quick delivery
Comes in a plastic case for organization

Cons

Bits are brittle and may break easily
Packaging is not sturdy
May not work well with titanium alloys
