-steel SP;
-centering tip;
-2 cutting edges (Z2);
-2 engravers (V2).
TIPS AND WARNINGS
-Make repeated shallow cuts by allowing the bit to cool for two or three seconds between passes. This will increase the life of your tool. Overheating caused by chip buildup or constant contact with the cutting surface will remove the hardness from the cutting edges of the bit.
-You can extend the life of your tool by not exceeding the maximum allowable rotational speed for the type of wood. Forcing the bit during machining can cause it to overheat.
-Remove chips from each machined hole before moving on to the next one.
-Small drill bits can be inserted into electric hand drills, but the results are not always satisfactory. Conversely, using a bit larger than 19mm in diameter with these drills can cause injury if the tool comes in contact with certain imperfections in the wood.
-Always wear eye and ear protection before using power tools.
Application
Execution of precise, square and well-smoothed holes on soft wood of any size. Drilling at any angle to create ovals or arched openings. Execution of niches for fixing guides or supports.
