Frequently Asked Questions

What is an HSSE insert and how does it differ from standard HSS?

HSSE (High Speed Steel with Cobalt) is high-speed steel with added cobalt (5–8%). Cobalt increases hot hardness and wear resistance: HSSE inserts better withstand the temperatures generated by tapping on tough materials like AISI 304 stainless steel, chrome-molybdenum steels, and hard cast irons. On mild steel and aluminum, the difference compared to standard HSS is minimal; on stainless steel and hard materials, tool life can be 3–5 times longer.

Is this insert compatible with my Bernardo threading machine?

Bernardo HSSE inserts are compatible with TM and STG series threading machines. Check your machine's spindle attachment (GT 12 or GT 24) before purchasing. For compatibility confirmation, contact Krollit. Customer support available in Italian.

What is the correct speed for tapping with an HSSE insert?

On mild steel S235: 10–15 m/min. On stainless steel AISI 304: 3–6 m/min with abundant coolant/lubricant. On aluminum: 15–25 m/min. Peripheral speed is calculated: n (rpm) = (v × 1000) / (π × d). Always use coolant/lubricant — HSSE inserts resist heat but wear out more quickly without lubrication.
