DRILLING TOOLS
Multi Drills
MultiDrill series is Sumitomo‘s original brand of high performance drills that have a special cutting edge design coupled with an advance carbide substrate. The series has a comprehensive selection of diameters and drill lengths to cover a wide range of work materials and require-ments, providing high efficiency, high precision and cost effectiveness.
- Unique curved flute design with proven enhanced chip formation and removal, resulting in better hole accuracy.
- High speed and high efficient drilling is made possible with the combination of a special substrate with an advanced PVD coating. (10x tool life of HSS drills, 5x the efficiency)
- Wide selection range (Diameter: 0,03–65 mm, Drilling depths L/D: 2–30)
- Other diameters and length can be asked and offered
SDP Type (DIN)
- The specific and optimum solution for a wide range of application conditions
- Top performance parameters, maximum feed and stable long tool life
- Double margin design for high-precision holes
- Good balance of high wear resistance and toughness
- Curved cutting edge – ideal for removing chips
- Reliable and high productivity performance
SDM Type
- High process reliability in stainless steel and low carbon steel
- Can be used on low-performance machines! (àavoids overload!)
- High surface quality in the bore
- Sharp cutting edge
- High adhesion resistance by Sumi-Power Coating
DEX Coating
- Sumitomo Electric Hardmetal‘s next-generation drill coating utilises nano-coating technology to provide more than double the tool life of conventional coatings.
- Silicon and chrome improve usure, heat, and adhesion resistance.
- New super multi-layered structure offers significantly improved chip resistance (coating strength).
Characteristics
Coating Design World‘s first combined super multi-layered coating is made from alternate layers of super multilayered substrates.
Extra Long SUPER MULTI-DRILLs : MDW … XHGS/PHT
Super MultiDrill XHGS series is a next-generation drill for deep hole drilling, features stable chip control and improved strength to further enhance efficiency of deep hole drilling.
Low Cutting Resistance
The application of a new special thinning shape „RX thinning“ reduces cutting resistance during high efficiency drilling.
Chip Control
New groove shape „J flute“ with improved chip control stability when drilling deep holes. Improved chip evacuation makes it possible to reduce spindle load fluctuation, ensuring stable, long tool life.
Replaceable Head Type MULTI-DRILLs : SMD Type
Fast accurate and ideal for drilling steels, this newly developed drill from SUMITOMO gives similar hole accuracy to that of regrindable drills renowned within the industry as being the ultimate hole making
tool.
- Available in diameters ranging from 12,0–42,5 mm
- Drilling Depths 1,5–12 x Diameter
- Optimised heat dissipation via precisely located coolant holes
- Maximised rigidity from newly developed clamping system
- High performance drilling of precision holes from solid
- 3 different types of head for general and smooth cutting (MTL type, MEL type)
and new MFS type for drilling in non-flat surfaces.
WDX Type
The SumiDrill WDX type has excellent cutting balance that provides stable hole drilling on a wide range of work materials from general steel to stainless steel and aluminium alloy. Available in four original chipbreaker styles, the inserts feature improved chip control and reduced cutting force for use in low rigidity contexts.
Design
Cutting force during drilling is balanced between central insert and peripheral insert. The relative position of each insert is optimised to provide stable drilling.
Excellent Chip Control
The chip evacuation direction can be controlled with the chip control groove at the centre of the breaker, enabling good chip control. Versatile Tool for a Variety of Machining Applications Select among four types of breakers for different applications, allowing optimal drilling for a variety of work materials and conditions. Suitable for a wide range of applications including hole expansion, spot facing, external turning and internal boring.
Economical Four-Cornered Insert
Inserts can be used in either central or peropheral positions with two corners for each position – a total of four corners.
Eccentric Sleeve WAS Type
The Eccentric Sleeve WAS Type, exclusively designed for ˮSumiDrill“ WDX Type, provides up to ± 0,3 mm of hole size adjustment.
