Metal drilling bits

Weldon clamping 19 mm Working length 30 mm Correct ejector: 6.34 x 77 mm (201261)   PRODUCT DETAILS: Core drills made from special HSS-XE steel + GOLD-TECH surface treatment. Gold-Drill Line drills are the most commonly used uncoated drills made from HSS-XE steel.   FEATURES: Made from high-alloy special HSS-XE steel. For exceptional hardness at the tips of the teeth [up to 68 HRC]. This ensures high wear resistance and long service life. GOLD-TECH surface treatment: special treatment for longer service life. Entirely ground from solid material. This fine grinding increases cutting performance while reducing friction. For longer service life.   Few manufacturers are capable of producing step-hardened core drills. For us, this is standard. This results in extremely hard tooth tips [68 HRC] while remaining a flexible core drill. Seven different blade geometries, optimized according to the diameter and depth of cut of the core drill, ensure the highest processing performance. For larger diameters see art. 201315 and art. 201316. For smaller diameters see art. 201230.   APPLICATION: Due to the special GOLD-TEC surface treatment + complete grinding + special HSS-XE steel perfectly suitable for drilling into steels up to 900 N and even stainless steels.

For clamping cross drills, drill bits with a 19 mm [3/4"] Weldon + Nitto shankMK2 attachment for the drilling machine

Crown drills made of special steel HSS-XE + surface treatment GOLD-TECHSET CONTENTS:Usable length 30 mm,Weldon shank 19 mm (3/4),6 HSS-XE core drills:1 piece each with diameters of 12, 14, 16, 18, 20, 22 mm2 ejector pins 6.34×77 mmFEATURES:Made from highly alloyed special steel HSS-XE. For exceptional hardness at the tooth tips [up to 68 HRC]. Therefore, high wear resistance and long tool life.GOLD-TECH surface treatment: special treatment for longer tool life.Fully ground from the entire material. This fine grinding increases cutting performance while reducing friction. For longer tool life.Only a few manufacturers can produce hardened core drills in stages.For us, this is standard. This achieves exceptionally hard tooth tips [68 HRC] while still maintaining flexible core drills.Seven different cutting geometries, optimized according to the diameter and depth of the core drill cut, ensure maximum cutting performance.APPLICATION:Due to the special surface treatment GOLD-TEC + full grinding + special steel HSS-XE, it is excellent for drilling in steels up to 900 N and also suitable for stainless steels.
