Advanced Carbide Tooling are the UK's exclusive distributor of Nine9 3xD Super Drills

Diameter range: 10mm - 30mm

Main features
• Smallest indexable drill from diameter 10 mm, 3xD
• Dual relief angle insert, maximum feed rate is possible
• Unique design of the central and peripheral insert position; the cutting chips are divided into more pieces, making swarf excavation more efficient
• The central insert and peripheral insert are identical, therefore insert costs are less and stock management is easier
• Better surface finish, better form accuracy.

Insert
• K20F grade carbide insert, fully ground, multi-layer TiAIN coated, universal type for all kinds of materials
• Fine lapping on the cutting edge, good chip breaking condition
• Patented dual relief angle insert
- Primary relief angle: 7˚ for increasing toughness of the cutting edge
- Secondary relief angle: 11˚ for increasing axial feed rate
• Square insert with 4 cutting edges meaning lower cost!

Insert position
Thanks to the specially arranged insert position, the cutting chips will be split into more pieces for optimised cutting chip removal flow.
The cutting edge of the insert is nearly perpendicular to the axial line, minimising the lateral cutting force. It helps to reduce chattering even on unstable drilling conditions.

Tough body
The body is made of high alloy tool steel
The body is hardened and nickel plated
Two drilled coolant holes help to supply a large volume of coolant to flush out the swarf.
