English Recommendations for Tool Operation • Large (5/16" to 1/2" [7.9 mm to 12.7 mm]) holes in steel can be made easier if a pilot hole (5/32" to 3/16" [4 mm to 4.8 mm]) is drilled first. • When drilling, always apply pressure in a straight line with the bit, but do not push hard enough to stall the motor or deflect the bit. A smooth even flow of material indicates the proper drilling rate. • If drilling thin material or material that is prone to splinter, use a wood "back-up" block to prevent damage to the work piece.
