NIETZ HSS TIN-COATED M2 1/2 REDUCES SHANK DRILL BIT - 56420

More info

NIETZ HSS TIN-COATED M2 1/2 REDUCES SHANK DRILL BIT - 56420, refers to an industrial-quality drill bit with specific features for heavy-duty metal drilling.

Here is a breakdown of the key specifications and features:

Product Details

Feature	Description
Material	M2 High-Speed Steel (HSS) - Known for its high hardness, wear resistance, and toughness, especially at high operating temperatures.
Coating	Titanium Nitride (TiN) Coated - This thin, ceramic coating reduces friction, increases cutting speed, and significantly extends the tool's lifespan (often 3-5 times longer than uncoated bits).
Shank Type	1/2" Reduced Shank - This allows larger diameter drill bits to be used in standard chucks (like those on a drill press or heavy-duty hand drill) that only accept up to a 1/2-inch shank. The overall drill bit diameter is likely larger than 1/2 inch (e.g., 13.5mm to 32mm).
Code Series	564-20-XXX (The 56420 is part of this series) - This series typically corresponds to the general-purpose, 1/2" shank, TiN-coated M2 drill bits.
Point Angle	Commonly 118° for this series (though some jobber bits are 135°), designed for general-purpose drilling in various materials.

Applications

This drill bit is designed as a general-purpose tool for professional workshops and metal fabrication.¹ It is suitable for drilling in materials such as:
