Precision Twist Drill HSS Core Drill Bit - Steam Tempered

Precision Twist Drill HSS core drill bits (also called core drills or steam oxide core bits) are made for enlarging existing holes. They suit cored, punched or pre-drilled holes in shop, fabrication and maintenance work. The high speed steel construction handles the heat and cutting speeds of machine drilling.

Key Features:

• High speed steel (HSS) construction for durability and wear resistance in metalworking.
• Steam tempered (steam oxide) finish helps keep workpiece material from sticking to the cutting surfaces. This supports cleaner, more accurate holes.
• Core drill design for opening up existing holes, not starting new ones.
• Precision Twist Drill quality for consistent performance in production and maintenance environments.

Steam tempered HSS tooling is a practical, general-purpose choice for drilling steel and other common workpiece materials. Choose the child item that matches your required size and specifications.
