Brute Platinum Heavy Duty Jobber Drills are ideal for drilling steel, stainless steel and tough alloys. XL5 drills outperform cobalt drills due to their ability to flex, when cobalt drills snap. 135 degree split point prevents the drill from walking for precise, accurate drilling every time. Proprietary NOMO surface treatment increases heat resistance, prolonging tool life. XL5 drills featured tapered web geometry for fast penetration and therefore, faster, more productive drilling.
