Item Description:

Product Information

Features: The M35 cobalt-containing step drill (HSS Co) is primarily designed for drilling wooden boards, aluminum plates, thin steel plates, and more, fulfilling tasks that ordinary HSS4241 step drills may struggle with. The M35 step drill is specifically suited for drilling stainless steel plates.

Key Points to Note:

• For drilling stainless steel, both hand drills and table drills are suitable. Hand drills are recommended for plates up to 1mm thick, while bench drills are preferable for plates ranging between 2-3mm in thickness.

• When drilling stainless steel, it's important to maintain a moderate speed, typically a few hundred revolutions per minute.

• Using water injection or cutting fluid cooling during the machining process is advisable, as it can significantly prolong the service life of the drill bit.
