10PCs Precision PCB Drill Bit Set (0.3mm–1.2mm) Tungsten Steel Carbide Bits for CNC & Electronics Work

Tired of cracked PCB traces, wandering drill bits, and ruined circuit boards? The Amicikart 10-Piece Precision PCB Drill Bit Set gives you tungsten steel carbide micro bits engineered for clean, burr-free holes — every single time.

This professional-grade set covers all 10 most-used PCB hole sizes from 0.3mm to 1.2mm in a single purchase, so you're never hunting for the right bit mid-project. Each bit is machined from premium tungsten carbide — a material significantly harder and more wear-resistant than standard HSS bits — delivering sharper cutting edges, reduced heat build-up, and a tool life that outlasts cheaper alternatives by a wide margin. Whether you're drilling through FR4 fibreglass, phenolic boards, or delicate multi-layer PCBs, these bits hold their geometry and produce consistently precise holes with minimal breakout.

Fully compatible with CNC drilling machines, PCB routers, and hand-held micro drill presses, this set is the go-to choice for electronics engineers, hobbyists, repair technicians, and DIY makers who demand sub-millimetre accuracy. A compact, labelled storage case keeps all 10 sizes organised, protected, and instantly identifiable — no more loose bits rolling off the workbench.

Backed by a 1-year warranty and Amicikart's dedicated support team (WhatsApp, call, or email), you get professional-grade tooling with zero-risk buying. Grab the complete set with free pan-India shipping, same-day dispatch before 2 PM, 30-day easy returns, and COD available.
