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

A­ chatter-free cutter giving an excellent burr-free finish. Capable of deburring and countersinking in one stroke with no ‘back-off’ of tool.
Also free countersinking of aluminium with no secondary bulge. For special applications and exotic materials, a choice of hard coatings is available.

The Kennedy® variable pitch hole saws deliver high quality holes in a range of materials, including wood, steel, brass, bronze, and cast iron. The M3 HSS cutting teeth aggressively cut to give a very smooth finish with little to no tear out.

Features and Benefits
• Cuts up to 40% faster than constant pitch saws
• Varying tooth pitch disrupts harmonics to substantially reduce noise
• Tooth life is extended when used in conjuction with a cordless drill

Typical Applications
• Construction
• Engineering
• Maintenance

Notes
• 4-6 teeth per inch
• 28.5mm (11/8") cutting depth
