Guhring 9002350050000 Extra Length Drill Bit Hss

Product Description

The GUHRING 9002350050000 is an extra length, two-flute spiral drill bit designed for deep hole drilling in metalworking applications. Built to DIN 1869 standards, it features a 5.00 mm (0.1969 inch) diameter with an h8 tolerance shank, a 118-degree drill point angle, and a web-thinned tip for reduced thrust and cleaner entry. The oxide finish provides basic lubricity and corrosion resistance during cutting. At 195.00 mm (7.68 inches) overall length with a 135.00 mm (5.31 inch) flute length, this bit reaches depths that standard-length drills cannot. It is sized and spec-built for use by machinists and tool-and-die professionals working in production or job-shop environments.

This bit is suited for deep hole drilling in cast iron, steel, and aluminum. The 10xD flute-to-diameter ratio and right-hand spiral make it well suited for through-holes and deep blind bores where chip evacuation is a priority. The straight-cylindrical shank fits standard drill chucks and collet holders. General-purpose grade construction makes it appropriate for a range of ferrous and non-ferrous workpiece materials in both manual and CNC drilling setups.

Key Features

• DIN 1869 extra length design with 10xD flute-to-diameter ratio for deep hole reach
• 118-degree drill point angle with web-thinned tip reduces entry thrust
• High speed steel construction with oxide finish for basic lubricity
• Straight-cylindrical shank with h8 diameter tolerance for precise chuck fit
• Right-hand cut, regular spiral flute for efficient chip removal
• No coolant-through design — suitable for flooded or dry cutting with appropriate feed rates

Compatibility

Designed for deep hole drilling in cast iron and steel (ISO material codes K and P) as primary workpiece materials, with aluminum (ISO code N) as a secondary application. Compatible with standard drill chucks and collet holders accepting a 5.00 mm straight-cylindrical shank.

Installation Notes

This drill bit is installed and operated by machinists, tool-and-die technicians, and CNC operators. Secure the shank fully in a drill chuck or collet holder before operation and verify runout before beginning a cut. Always power down the spindle and bring it to a complete stop before changing or inspecting the bit. Do not exceed the maximum drilling depth of 5.0200 inches (127.50 mm) in a single pass without a peck-drilling cycle to clear chips.
