Ever lined up your drill on stainless steel or alloy, only to watch it skate across the surface? That frustration ends with this 1mm spotting drill bit. Designed for spot-on accuracy, it punches clean 60-degree countersinks right where you need them, setting up full drills for success without the guesswork.
Machining steels below HRC60—like carbon steel, die steel, or stainless—demands tools that won't dull fast or vibrate. Standard bits often slip, chip the workpiece, or wear out mid-job, wasting time and material. You need something tough enough for repeated use in CNC centers, engraving machines, or lathes.
Crafted from fine-grained tungsten carbide (HRC92 hardness), this bit laughs off wear and heat. The AlTiSin coating boosts hardness, lubricity, and thermal stability, letting you push cutting speeds higher than with uncoated tools. Key specs include:
The universal chamfered shank grips tight, minimizing runout for smoother operation.
Expect longer tool life—up to 5x that of HSS bits—and faster feeds without sacrificing finish quality. Cuts stay neat and burr-free, reducing cleanup time. Vibration drops thanks to balanced design, so your workpiece stays flat and accurate. It's not just a starter tool; it improves overall drilling performance by guiding larger bits perfectly.
Fire it up on your CNC mill for prototyping circuit boards, aerospace parts, or custom knife blanks. Precision engravers love it for marking or shallow holes in hardened molds. Hobbyists drilling tiny holes in RC car chassis or model engines get pro results. Pro tip: Clamp at least half the length for best rigidity; dial back speed if shorter to avoid chatter. Pair with appropriate coolant for stainless to max out life.
At 1mm, it's ideal for fine work where bigger spotters overpower. Feel the difference: smoother feeds, crisper edges, fewer rejected parts. Add this carbide spotting drill to your toolkit and watch your machining efficiency climb.
