A standard 118° conventional point is better suited to mild steels and free-machining materials.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Are these drill bits suitable for use in handheld power tools?\u003c\/strong\u003e\u003cbr\u003eA: Yes. The 400F set is specifically listed for drilling with handheld power tools. The 3-flats shank reduces slippage in drill chucks, and the self-centering split point aids accuracy when a drill press or fixed setup is not available.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What surface treatment do these bits have, and what does it provide?\u003c\/strong\u003e\u003cbr\u003eA: These bits feature a black oxide surface treatment, which reduces friction and heat damage during drilling and increases tool life. Black oxide is appropriate for performance on low to medium tensile strength materials.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What are the critical factors for maximizing drill bit performance and life?\u003c\/strong\u003e\u003cbr\u003eA: According to Drillco, speed, feed, and lubrication are all critical to cutting tool performance. Using the correct combination of these parameters for the material being drilled will extend bit life and improve hole quality.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Where are these drill bits manufactured?\u003c\/strong\u003e\u003cbr\u003eA: The DRILLCO 400F 29 PC Drill Pal Set is manufactured in the United States.
