Drills

The general-purpose drill line from Dormer Pramet includes the Precision Twist Drill brand of Silver & Deming drills. These reduced-shank drills deliver versatility and reliability.

MK Tools’ solid-carbide round tools from Monaghan Tooling Group introduces new “Speed-Drill R4” geometry, reportedly offering unparalleled cutting speeds and unprecedented tool life in gray cast iron, ductile iron and forged steel—all popular materials in automotive engine and chassis components. With a new corner radius design, which is tangential to the drill point but nontangential to the diameter, these proven designs address challenging, high-production drilling applications.

Alfa Tools introduces tungsten carbide-tipped hole cutters for cutting many different types of materials, including construction steel plate, stainless steel, iron, aluminum, copper, cast iron, fiberglass and plastics.

For best results in the machining of multiple material layers, cutting parameters must be applied for each different material. The new L-MAX, a portable drilling unit from SOMEX, a member of the SUHNER group of companies, can perform all of these functions in automatic mode.

Microcut, a manufacturer and distributor of miniature and microsized carbide cutting tools, has produced a 180-page catalog, It includes new lines of variable-helix 3-flute endmills in long-reach, long-shank, long-flute and corner-radius versions. In addition, 272-degree spherical endmills, miniature long-reach corner-rounding endmills, and 82-degree drill point mills are offered.

The Tritan-Drill, the 3-flute drill from MAPAL, achieves more bores, a longer tool life and lower machining costs compared with its twin-fluted companion. The Tritan-Drill makes it possible to machine with a significantly higher feed rate. In both standard and special designs, it combines process reliability and high performance.

Walter has introduced the Walter Titex DB133 Supreme, a solid-carbide microdrill that reportedly delivers tight tolerances, high-quality surface finishes, superior process reliability and longer tool life. The difference for the DB133 Supreme begins with the use of grades WJ30EL and WJ30ER, developed by Walter specifically for microdrills.

Darex LLC has recently unveiled the XPS-16+ CNC drill sharpener. This unit can sharpen 2-flute HSS, cobalt, carbide and TiN-coated bits from 3mm to 16mm in diameter.

Alfa Tools offers Blitz Nitride jobber drills for heavy-duty production work, as well as tough maintenance (MRO) applications. These extra heavy-duty drills can tackle applications in the widest range of materials, including mild steel, stainless steel, titanium and nickel alloy steels, as well as nonferrous materials.

Taurus Tool & Engineering is manufacturing new lines of drills and countersinks to support the aerospace industry. Each tool is designed with a specific flute geometry for increased chip flow and minimal exit burrs, as well as to prevent any swirl marks on aluminum skins.
