Why Good Steel Is Only the Beginning
Series: Why Drill Bits Fail | Article 1 Keywords: HSS drill bits, M35 cobalt drill bits, drill bit material quality, drill bit manufacturing, high speed steel When buyers ask about drill bit quality, the first question is almost always about material. “Is it HSS?” “Is it...Read more -
Drilling stainless steel: what you need to get right
Stainless steel is one of the most demanding materials to drill. Unlike mild steel or aluminium, it punishes poor technique and wrong tooling quickly and visibly — through broken bits, oversized holes, and rough surface finishes. This guide explains why stainless steel b...Read more -
DIN 333 Type A vs. Type B Center Drills: How to Choose the Right One
When engineers and buyers specify a DIN 333 center drill, one of the most common questions we receive is: "What's the difference between Type A and Type B — and which one do I actually need?" It's a fair question. Both types share the same 60° chamfer angle, follow the s...Read more -
What Are M42, M35, and M2 HSS Drill Bits? A Practical Guide to Choosing the Right Grade
When buyers ask us about HSS drill bits, one of the most common questions is: "What's the difference between M42, M35, M2 — and what about 4341?" It's a fair question. All of them are high-speed steel (HSS) materials, and on the surface, they look nearly identical. But t...Read more -
What Are Double-Ended Drill Bits?
Introduction In metal fabrication and industrial drilling, tool life and procurement cost are two of the most critical factors for buyers. Double-ended drill bits — also known as reversible drill bits or twin-point drill bits — offer...Read more -
Why Stable Supply Matters More Than Low Price in 2026: A Guide for Industrial Tool Buyers
When sourcing industrial tools — especially HSS drill bits and cutting tools — most buyers start with the same question: "Who has the lowest price?" It's a reasonable instinct. But in 2026, it may be the wrong question. The Market Has Changed ...Read more -
How to Prevent Drill Bit Wandering: A Complete Guide for Precision Metal Drilling
When drilling into metal, one of the most frustrating problems is encountering a drill bit that slips or "walks" across the surface at the start. In the industry, this issue is known as drill bit wandering (or walking). Wandering prevents the creation of a perfectly conc...Read more -
Why Cobalt Drills Are Irreplaceable in High-Heat Stainless Steel Machining
In the world of industrial metalworking, stainless steel is known for its extreme "toughness." Whether you are working with 304, 316, or specialized 400-series alloys, these materials create a major challenge for standard cutting tools: intense, localized heat. At Jiache...Read more
