: Most GOST bits are crafted from R6M5 (high-speed steel with tungsten and molybdenum) or P18 (high tungsten). These alloys are designed to maintain hardness even at high temperatures.

Even the best GOST-certified bits require care. Always use when drilling metal to prevent overheating, and ensure you are using the correct RPM for the diameter of the bit. A GOST bit can be sharpened many times over its lifespan, making it a much more sustainable investment than disposable "bargain" sets.

When shopping, look for the following markings directly on the shank of the drill bits: : (e.g., GOST 10902-77). The Steel Grade : Look for markings like Р6М5 or HSS .

: Some GOST-compliant bits undergo additional surface treatments to reduce friction and prevent "chip welding," extending the life of the tool significantly. How to Spot a Genuine GOST Set

The GOST standard (specifically for cylindrical shank twist drills) originated as a rigorous quality control system. Unlike generic "high-speed steel" bits that may vary wildly in quality, GOST bits must adhere to strict manufacturing protocols:
