## Description

Product description

Review: Worked great for boring through an M3 screw. - So I bought these because I had a stripped-head M3 screw that was stuck (due to purple thread lock having been used). I needed something to drill out the old screw so that I could re-tap the hole and salvage the expensive aluminum part. These bits definitely did the trick. I broke 4 of them in the process, as they are very fragile and rigid. But they were plenty sharp enough to cut into the stainless screw head and bore down through the center of the screw. No drifting, no damage to the surrounding aluminum part. Just straight through. I found it works best to set the dremel to a slower speed and be patient so as not to break or overheat the bits. And keep it as straight as possible to avoid flex. But I'm super happy, I have a bunch left just in case this ever happens to me again!
Review: They drill through hardened steel - They are brittle (obviously) but I used only 4 bits (first try) to drill a hole through hardened steel knife blade! I’ve never seen drill bits this good sold at any other hardware stores! Not to mention the price I paid was nearly nothing compared to those brick and mortar chain stores ! I’d the price stays low I’ll keep coming back!!

## Features

- PACKING LIST: Micro drill bit set contains various sizes of drill diameter, 0.15mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, each size has 1 piece, total of 10 pieces. NOTE: color is random
- FEATURE: Our carbide twist drills combine ​92% Tungsten Carbide / ​​8% Cobalt for extreme hardness (HRA 89-95), wear resistance (3x HSS life), and heat stability (800°C+). Featuring razor-sharp cutting edges and precise milling grooves, ensuring maximum productivity and durability in demanding applications.
- APPLICATION: With their high hardness, wear resistance, and precision machining capabilities, cemented carbide mini drill bits are widely used in high-precision applications, including electronics manufacturing (PCB micro-hole drilling), precision machinery (micro-component processing, micro-hole machining)
- INSTRUCTION: Make sure the workpiece is firmly clamped (such as using a vise or fixture) to prevent it from sliding during drilling. Position the twist drill at 90° to the workpiece. For thick materials, drill in multiple passes to prevent overheating or breakage.
- NOTE: When machining different materials, the spindle speed and feed rate vary. Generally, the harder the material, the lower the spindle speed and feed rate should be. Always use coolant in high-speed machining to protect carbide tools from heat-induced failure.
