Heavy Duty Web Construction

Type “B” drills are made with a heavy web construction and may be used with heavier
feeds in harder materials. Because of torsional strength and a 135° split point, this drill is
popular in hand held drilling applications to reduce breakage and eliminate skidding or walking.
