It allows the drills to be used on most materials.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why is a 135° split point preferred over a 118° conventional point for this application?\u003c\/strong\u003e\u003cbr\u003eA: The 135° split point is self-centering, which reduces walking when starting a hole and lowers the thrust required to penetrate the material. This makes it especially effective for handheld drilling on curved surfaces and for harder materials where a conventional point would tend to skate.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can these drills be used in CNC machines as well as handheld drills?\u003c\/strong\u003e\u003cbr\u003eA: Yes.

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.

The black and gold surface treatment also makes it suitable for use on most materials.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why does this set use a 135° split point instead of a conventional 118° point?\u003c\/strong\u003e\u003cbr\u003eA: The 135° split point is self-centering, which reduces walking on contact — especially important on curved or hard surfaces — and reduces the thrust required to drill. A conventional 118° point is better suited to mild steels and free-machining materials, while the 135° split point is preferred for harder materials and hand-drilling applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the advantage of the black and gold surface treatment over black oxide?\u003c\/strong\u003e\u003cbr\u003eA: The black and gold surface treatment provides better resistance to corrosion and breakage, increases lubricity, and reduces chipping and flaking compared to black oxide. Black oxide is generally suited to low to medium tensile strength materials, while black and gold is rated for most materials.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What sizes are included in the 800A25 set?\u003c\/strong\u003e\u003cbr\u003eA: The set includes 25 metric sizes from 1mm to 13mm in 0.5mm increments, covering the full range of common metric drill sizes in a single kit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Are speed, feed, and lubrication important when using these bits?\u003c\/strong\u003e\u003cbr\u003eA: Yes — DRILLCO specifically notes that speed, feed, and lube are all critical to cutting tool performance.

They are not intended for hardened steels, stainless steel, or other high-tensile-strength materials — cobalt or bronze-treated drills are recommended for those applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why does the black oxide surface treatment matter?\u003c\/strong\u003e\u003cbr\u003eA: Black oxide reduces friction and heat damage, prevents chip welding to the cutting edges, improves chip flow out of the flutes, and increases abrasion resistance — all of which extend tool life compared to bright-finish drills when working low to medium tensile strength materials.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the significance of the 118° conventional point angle?\u003c\/strong\u003e\u003cbr\u003eA: The 118° conventional point is optimized for mild steels and free-machining materials, providing rapid penetration. For curved surfaces, hand-drilling on harder materials, or applications where self-centering is critical, a split-point drill (118° or 135°) would be more appropriate.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Are speed, feed, and lubrication important when using these drills?\u003c\/strong\u003e\u003cbr\u003eA: Yes — per Drillco's technical guidance, speed, feed, and lubrication are all critical to cutting tool performance.

premium grade carbide, delivering increased performance and tool life on both ferrous and non-ferrous materials. Its portability makes it a practical choice across multiple trades, and the broad size range from 9\/16\" to 4\" means a single product line can cover the majority of large-diameter hole cutting requirements on a jobsite. For applications requiring deeper cuts in thicker material (up to 1\"), DRILLCO's companion 9600CT model is available.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features \u0026amp; Benefits\u003c\/h3\u003e\n\u003ch4\u003ePremium Grade Tungsten Carbide Teeth\u003c\/h4\u003e\n\u003cp\u003eThe ultra-hard tungsten carbide cutting teeth are manufactured from premium grade carbide, providing increased performance and extended tool life compared to standard bi-metal alternatives.

It is a High Speed Steel (HSS) tool, which is suitable for general purpose drilling in these material categories.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the advantage of the screw machine (stub) length over a standard jobber-length drill?\u003c\/strong\u003e\u003cbr\u003eA: Screw machine length drills are shorter than jobber-length drills, which provides greater stability, reduces deflection, and mitigates breakage. They are also better suited for drilling in tighter, more confined spaces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What does the 135° split point do, and why does it matter?\u003c\/strong\u003e\u003cbr\u003eA: The 135° split point reduces walking at the point of entry, allowing the drill to self-center without requiring a center punch. This improves hole placement accuracy, particularly on curved surfaces or when hand-drilling.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What size range is available in the 380 Series?\u003c\/strong\u003e\u003cbr\u003eA: The 380 Series is available in wire gauge sizes #1 through #60, with individual item numbers 380A001 through 380A060.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Are speed, feed, and lubrication important when using these drills?\u003c\/strong\u003e\u003cbr\u003eA: Yes.

For standard-length burrs: 1\/4\" — 70,000 RPM; 5\/16\" — 68,000 RPM; 3\/8\" — 66,000 RPM; 7\/16\" — 58,000 RPM; 1\/2\" — 50,000 RPM; 5\/8\" — 40,000 RPM. For 6\" long burrs, maximum speeds are halved (e.g., 1\/4\" — 35,000 RPM). For safety reasons, never use 6\" tungsten carbide burrs below 20,000 RPM.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What burr shapes are available in the 7000 series?\u003c\/strong\u003e\u003cbr\u003eA: The 7000 series is available in twelve USCTI shapes: Cylindrical (SA), Cylindrical End Cut (SB), Cylindrical Round Nose (SC), Ball (SD), Egg (SE), Tree (SF), Tapered (SG), Flame (SH), Cone 90° (SK), Cone (SL), Conical (SM), and Inverted Cone (SN).\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What shank sizes are available, and are these compatible with pencil grinders?\u003c\/strong\u003e\u003cbr\u003eA: The 7000 series is available with 1\/4\" shank diameter for standard die grinders and 1\/8\" shank diameter for use in pencil grinders (miniature sizes).
