I use them to drill holes in RC body shells. Has a nice clean hole. ### ⭐⭐⭐⭐⭐ Fast delivery *by J***S on February 3, 2026* great product ### ⭐⭐⭐⭐ Initial impressions *by R***M on January 19, 2026* Haven't had a chance for thorough testing in multiple materials, but the edges on these bits seem like they'll probably do okay in wood and plastic... metal might be iffy. The included pouch, while a nice touch, came with inadequate hook & loop to hold the pouch flap closed and secure the bits. And what little hook & loop was there wasn't fully attached. Therefore one of my brand new bits fell onto the tile floor (not good for my bit or my tile). ## Frequently Bought Together - Step Drill Bit Set, 3 Pieces Titanium Coated High Speed Steel Unibit Cone Drill Bit Kit for Plastic, Wood, Metal Sheet, Aluminum Hole Drilling Stepped Driil Bit (Metric 4-12mm/4-20mm/4-32mm) - MOLOTOW ONE4ALL Acrylic Paint Marker, 2mm, Cool Grey Pastel, 1 Each (127.218) - Vallejo - Wash FX | Light Rust 35 ml.
