HSS multi diameter step drills produce good quality holes in a wide variety of sheet metal, using either a bench drill or light pedestal drilling machine. Manufactured from high speed steel, they offer sound rigidity, strength and stability when machining. Each tool cuts parallel holes in a range of specific sizes and is compatible with materials up to 1/8" (3mm) thick.

Features and Benefits
• High speed steel construction for greater strength, rigidity and stability
• Excellent wear and heat resistance for prolonged tool life
• Cuts parallel holes in sheet metal

Typical Applications
• Drilling
• Sheet metal

Notes
• Available sizes 1-12mm to 6-37mm

Series L100 HSS straight shank long series drills are excellent general purpose drills which are designed to drill steels with tensile strength up to 1,000N/mm2, cast steel, grey cast iron, malleable cast iron, nickel brass and graphite.

Features and Benefits
• Manufactured from HSS for improved toughness
• Black oxide coating for greater heat and wear resistance
• Ideal for general purpose drilling

Typical Applications
• Drilling
• Steels
• Grey cast iron
• Malleable cast iron
• Nickel brass
• Graphite

Standards
• Manufactured to BS 328; Part 1: 1986, DIN 340 RN, ISO 494

TCGT turning inserts feature a CVD coated substrate providing an excellent general purpose grade for medium roughing on steels, stainless and cast irons.

Features and Benefits

The J100 Series are general purpose HSS straight shank drills with a black oxide finish. Ideal for applications involving steel (including cast steel) cast iron (including malleable cast iron) as well as nickel, brass aluminium alloys and graphite. Their 118° point allows for precise hole alignment and reliable cutting performance whilst the black oxide coating helps reduce heat by retaining coolant on the tool surface. The coating also helps reduce the risk of the tool staining.

Features and Benefits
• High speed steel construction for increased tool durability
• Point angle of 118° for precise holemaking and precision cutting
• Black oxide coating helps aid chip flow, reduce heat and prevent staining
• Ideal for applications involving steel, iron, nickel, brass, aluminium alloy and graphite

Typical Applications
• Cutting and drilling
• Ferrous materials
• Steel
• Iron
• Nickel
• Brass
• Aluminium alloy
• Graphite

Notes
• Available in sizes 0.25mm -20.00mm

Standards
• Manufactured to BS 328/DIN338RN
