Spiral Drill DIN 338 Thread-Rolled 11.8 mm

• Thread-rolled spiral drill bits made of high-performance high-speed steel.
• The thread-rolled spiral drill bits ensure increased resistance to breakage.
• High-performance spiral drill bits for all normal drilling jobs with all common materials.
• Applications: for alloy and non-alloy steel and cast steel (up to a strength of 900 N/mm²), grey cast iron, malleable iron, ductile iron, die-cast, sintered iron, nickel silver, graphite, short chip aluminium alloys, brass and bronze.
• Packaging unit: in plastic packaging

High-performance rolled, steam-treated twist drill made from heavy-duty high speed steel. The manufacturing procedure (no structural disruption) solidifies the material making it more elasticated. This makes it more resistant to fracture and suitable for robust drilling units (e.g. hand-held drilling machines).
