3/16 HSS step drill bit from True Position is a black and gold jobber length drill bit designed for accurate metal drilling and durable performance in wood. The special Hi-Molybdenum tool steel construction provides strength under demanding drilling conditions, so holes stay consistent through harder materials. A 135 degree split point starts accurately without a center punch, which reduces walking on metal and saves setup time. The bit is precision ground at the point, flutes, body, clearance, and drill diameter, creating smooth chip evacuation that supports cleaner holes. Body and clearance areas have a gold surface treatment for maximum lubricity, helping the bit cut with less friction. The drill is heat treated to 2,185 F and then nitro-carburize finished at 950 F, creating steel measurably harder than standard high speed steel for extended sharpness.
The 135 degree split point on this 3/16 inch jobber length drill bit helps the tip bite quickly into metal, limiting skating on smooth surfaces and supporting accurate hole placement. Precision grinding of the point, flutes, body, clearance, and diameter helps the bit track straight, which contributes to holes that better match layout for hinges, brackets, and other components. The gold-treated body and clearance areas reduce friction against the hole wall, helping chips clear efficiently and reducing the likelihood of binding. Nitro-carburize hardened steel tolerates higher drilling temperatures, so the cutting edges stay effective longer when drilling into work hardening grades of stainless steel or other hard metal applications. The bit is also described as ideal for solid woods, giving a consistent cutting feel when moving from metal components to wood members in the same assembly.
This True Position 3/16 HSS step drill bit is described as ideal for metal drilling, so it fits tasks that involve drilling through brackets, plates, or hardware made from stainless steel and other hard metals. The special Hi-Molybdenum tool steel supports drilling in work hardening grades of stainless steel, so holes can be created in tougher alloys used in shop fixtures and structural components. Its performance is also described as having exceptional durability drilling wood and as ideal for solid woods, which suits layouts where fasteners pass through steel and into hardwood or softwood members. The jobber length format offers a familiar reach for typical metal and wood drilling setups, so operators can use existing drilling stations or hand drills while benefiting from the bit's material and point geometry.
The precision ground point, flutes, body, clearance, and drill diameter are designed to provide accuracy and performance, helping each hole match the intended size for bolts, screws, or pins. The 135 degree split point promotes accurate starting without a center punch, which supports faster repetitive drilling along jigs or templates where layout marks are pre-established. Body and clearance areas treated with a gold surface for maximum lubricity lower friction against the hole sides, so the bit advances more smoothly and chips flow more freely. Heat treatment to 2,185 F followed by a nitro-carburize finish at 950 F results in steel that is measurable harder than high speed steel, supporting longer cutting life in sequences where drilling heats the bit. The nitro-carburize steel is described as able to withstand substantially higher drilling temperatures while maintaining sharpness, which helps maintain hole quality over extended runs in hard metals and solid woods.
