bend or break and may damage the work piece.
5.Back off your pressure when you are about to penetrate the work piece.
6.Keep the motor running when pulling the bit out of a completed hole to prevent the bit from jamming.
Metal Drilling
1.Use high speed steel, carbide or specialty bits for metal drilling.
2.Secure the work piece to keep it from moving during the drilling operation.
3.Use a punch to create a dimple for the bit to start.
4.Start by drilling slowly to keep bit from moving away from your starting point.
5.As the hole is established, increase tool speed. Do not go so fast or use so much pressure that the bit heats up. This can damage the bit and create an irregular hole. For hard metal or thick pieces, use cutting oil to keep the bit cool.
6.Since drilling in metal is a slow operation, you may lock the Trigger in the ON position to maintain a constant speed and reduce fatigue.
7.When drilling large holes in metal, start by drilling a smaller pilot hole, then using a larger bit for the final size hole.
Wood Drilling
1.Use high carbon bits or bits specially designed for wood drilling, such as brad point, spade bits, forstner bits, etc.
2.Secure the work piece to keep it from moving during the drilling operation.
3.Start by drilling slowly to keep the bit from moving away from your starting point. Increase speed as the hole is established.
4.To prevent or reduce “break out” when the bit penetrates the work piece, clamp a piece of scrap material to the back of the work piece.
5.Do not lock the Trigger in the ON position, as the bit can easily jam in wood and the motor must be stopped quickly.
