HSS Drill Bit 1/2-inch Parallel
HSS drill bits with 1/2-inch parallel shank provide secure chuck gripping for larger drilling applications in industrial workshops. Manufactured to DIN 338 standard, these drill bits deliver reliable cutting performance in steel, cast iron, and non-ferrous metals. The 12.7mm (1/2-inch) parallel shank ensures positive drive in standard drill chucks while the jobber-length flute design provides efficient chip evacuation and stable cutting geometry.

Industrial HSS Drilling Tools with 1/2-inch Parallel Shank
HSS drill bits with 1/2-inch parallel shank are designed for workshops requiring larger shank diameters for secure chuck mounting during heavy drilling operations. The 12.7mm parallel shank provides maximum gripping surface in standard drill chucks, eliminating slip and ensuring concentric rotation at higher feed rates. These bits are ideal for structural steel fabrication, marine repair work, and general engineering where larger drills are needed with standard chuck compatibility.
Manufactured from premium HSS with precision-ground flutes, these drill bits deliver consistent hole quality and extended tool life across a wide range of ferrous and non-ferrous materials. The jobber length configuration balances rigidity with chip clearance, making these bits suitable for both manual drilling and machine-mounted operations.
For high-temperature alloy drilling, consider our HSS Cobalt Drilling Tools with enhanced red hardness for stainless steel and titanium applications.
