Senator jobber drills are roll forged from HSS, ensuring uninterrupted grain structure. This provides exceptional strength and durability. Tips are ground for effective cutting. Suitable for drilling wood, plastic, carbon and plain steels where the cutting efficiency of ground flute is not required.

Features and Benefits
• HSS construction for increased rigidity
• Ground tips for effective cutting performance
• Ideal for use on a range of substrates including wood, plastic, carbon and steels

Standards
• Manufactured to DIN 338 Type N

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

Suitable for precision grinding of carbide, gems, glass, ceramics, tough alloys, cermets and tool steels, these diamond coated burrs are extremely durable.

Features and Benefits

• Recommended operating speeds 15,000 - 30,000 rpm
• Diamond coating offers extreme resilience and precise cutting

Typical Applications
• Suitable for precision grinding of carbide, gems, glass, ceramics, tough alloys, cermets, tool steels

Series J100 - Metric general purpose drills for steels, cast steel, grey cast iron, malleable cast iron, nickel brass, aluminium alloy and graphite.

Features and Benefits
• High speed steel construction with bright finish for increased toughness
• Supplied in the as-ground condition for use with non ferrous materials

Standards
• Manufactured to BS 328/DIN338RN

Notes
• Drills with a bright finish are supplied in the as-ground condition and such tools are used generally in the machining of non-ferrous materials.
