Frequently Asked Questions
Q1: What materials are these HSS twist drill bits suitable for?
A: These drill bits are designed for high-performance drilling in metal, wood, and various plastic materials.
Q2: What is the benefit of the Tin (Titanium Nitride) coating?
A: The Tin coating significantly increases surface hardness, reduces friction, and enhances the overall life of the drill bit by preventing heat build-up.
Q3: What does "Fully Ground" process mean for quality?
A: Fully ground drill bits are manufactured with higher precision, offering better chip removal and straighter holes compared to rolled or forged bits.
Q4: Why use a 135° split point instead of a standard point?
A: The 135-degree split point is self-centering, which prevents the bit from "walking" on the material surface and requires less thrust force to begin drilling.
Q5: What sizes are available in this series?
A: We offer a comprehensive range of sizes from 1mm up to 20mm in jobber length.
Q6: What is the typical lead time for an order?
A: Our standard production and delivery cycle is between 30 to 45 days depending on order volume.
