Drilling Sprung Steel Made Easy | TTP HARD Cobalt Drill Bits + CUT-IT Paste

Sprung Steel Drill Bit Demo

Sprung steel is one of the most difficult materials to drill. Its strength and spring tension make it punishing on standard drill bits, which overheat, dull, or break quickly. Nathan from Wales discovered this firsthand — burning through 15 “off-the-shelf” cobalt drill bits to make just 4 holes in sprung steel handles. After switching to TTP HARD cobalt drill bitsand CUT-IT cutting paste, he completed multiple holes with ease using just a single bit.

Key Highlights from the Video

• Nathan’s real-world test drilling 3mm holes in sprung steel handles

• 15 standard cobalt drill bits vs. 1 TTP HARD cobalt drill bit

• CUT-IT paste used to prevent overheating and friction

• Four drilling tips shown for success on tough steels

• Demonstrates efficiency, durability, and cost savings

Sprung steel is designed for resilience and shock absorption, making it a nightmare for drilling. Ordinary HSS or even standard cobalt drill bits heat up quickly, lose sharpness, or snap after just a few holes. This video demonstrates the performance difference with TTP HARD cobalt drill bits.

Nathan’s test shows that while 15 standard cobalt bits managed only 4 holes, a single TTP HARD bit, combined with CUT-IT metal cutting paste, drilled multiple holes smoothly. The difference? Proper metallurgy and correct technique.

The video also highlights 4 top tips for drilling hard metals:

1. Drill at a slow speed to avoid overheating.

2. Apply only necessary pressure — let the bit cut, not rub.

3. Use plenty of lubricant, especially a paste like CUT-IT that stays on the bit.

4. Drill in short bursts, withdrawing the bit to clear swarf and cool.

By following these steps, even a material as unforgiving as sprung steel can be drilled with confidence, saving time, money, and frustration.
