From the brand, the product description for the Mini Chainsaw Leaf Blower is as follows:

The 115-piece drill bit set features a wide range of sizes, from 1/16" to 1/2", allowing users to tackle a variety of projects. Additionally, the set includes 29 left-hand drill bits, as well as 13 pieces ranging from 1/16" to 1/4".

Crafted with M35 cobalt, the drill bits are durable, sharp, and robust, making them suitable for cutting through stainless steel, iron castings, copper, aluminum, and other soft metals, as well as plastics and wood. The 135-degree point tip and twist design facilitate faster cutting, while the self-centering feature prevents the bit from walking off and ensures efficient chip and particle removal.

The HSS (High-Speed Steel) drill bit set offers excellent cutting performance, particularly for hardened steel. The 29 drill bits are designed for long-term use, with hardened and polished inserts that provide improved sharpness and precise cutting without any wobbling.

For convenient storage and organization, the drill set includes drill holders with size indexes, and the entire package is compact and strong, making it easy to store and sort the bits as needed. If you have any questions, the brand encourages you to reach out, and they will be happy to assist you.
