The 3HP Jiffy STEALTH STX ice augers feature the serrated Ripper blade system with power point and black D-Ice#39;r ARMOR, which gives you an auger blade lasting 2-3 times longer than any other on the market. The STEALTH STX is great for initial drilling as well as redrilling of iced over holes. The Stealth STX features a 12:1 high-speed gearbox and uses special low temperature lubricant and PTFE on the friction surface, which enhances the performance in extreme cold weather to -65�F.
