FEIN HM-Ultra 35 QuickIN kovametallireikäsaha 28 mm 63127102017

For professionals who demand clean, precise holes in tough metals without the slowdown of conventional twist drills, the FEIN HM-Ultra 35 QuickIN core drill bit brings carbide-tipped cutting edges and a tool-free QuickIN shank to your magnetic drilling machine. This 28 mm annular cutter removes only a ring of material, so you get faster drilling, lower power consumption, and a reusable slug instead of a pile of chips.

Highlights

• Carbide (HM) tipped cutting edges for exceptional wear resistance in steel, stainless steel, and non-ferrous metals
• QuickIN tool holder system enables fast, secure bit changes without additional tools
• 35 mm cutting depth handles plates, profiles, and stacked materials in one pass
• Internal coolant supply directs fluid to the cutting zone for cooler operation and longer tool life
• Four cutting edges distribute load evenly, reducing vibration and improving hole quality

In daily use

On a fabrication site or in a maintenance workshop, this bit pairs with FEIN magnetic core drilling machines that have a QuickIN holder. The annular design requires less thrust than a solid twist drill, so the machine works more efficiently and the operator experiences less fatigue. The 28 mm diameter is a common size for cable entries, pipe penetrations, and structural bolt holes. Because the bit is optimized for high drilling speed, you can complete repetitive hole patterns quickly without sacrificing accuracy. The internal coolant supply is essential when working with stainless steel, where heat buildup can quickly dull standard HSS cutters.
