Spiraalboor KWB 258650 rechtsdraaiend 1 stuk

Spiral cutting drill bit KWB 258650 is an HSS M2, right-hand, cylindrical-shank drill designed for drilling in stainless steels and general steel, cast iron and cast steel. The drill has a 130° point angle with a specially polished section and a Quick Cut spiral geometry that produces small swarf while ensuring easy chip evacuation. Reinforced core, robust construction and a short spiral notch give the bit high heat resistance and stable cutting performance, suitable for use with cordless and corded drilling machines.

Advantages

The KWB 258650 combines an HSS M2 material with a reinforced core and special polished spiral that improves cutting action and reduces friction. The 130° point with a Quick Cut geometry produces small chips for clean evacuation and reduced clogging. The extra robust design and short spiral notch enhance durability and allow energy-saving, low-effort drilling with both cordless and tethered machines.

How to use

Secure the KWB 258650 drill bit in the drill chuck with the cylindrical shank fully seated. Select appropriate speed for HSS in the specific material (lower speeds for stainless steel). Use steady feed pressure and allow the Quick Cut geometry to remove chips; withdraw occasionally for deep holes to clear swarf. Apply cutting fluid when drilling stainless steel or hard materials to reduce heat and extend tool life.

Recommendations

For best results drill at recommended HSS speeds for the material, use cutting lubricant when working with stainless steel, and avoid excessive feed that can overload the bit. Replace the bit when wear or chipping reduces drilling accuracy.
