2.HSS twist drill

 

1)high speed steel Jobber drills to DIN388

   *right hand spiral round flute,drill points:118 degree and 135 degree

   *DIN1412C split point for more accure centering

 

2)HSS DIN338,standard,reduced shank

  * right-hand cutting type  N

   *high-performance high-speed steel

   *short,cylindrical

   *118 degree conical section

    *diameteral tolereance H8

    

3)HSS DIN340 ground,long

  *profile ground

  *right-hand cutting,type N

  *high-performance high-speed steel long,cylindrical

 

4)HSS DIN1869 ground extra long

 

5)hss DIN345 morse taper

 

6)hss DIN1897 pilot drill bits extra short

 

7)hss DIN8037 carbide tipped

 

3.step drills

*produced good quality holes in a wide variety of material.Produce specific size,parallel holes

*enlarging holes in sheet metals without the need of center punch or pilot.Using either a bench drill or light pedestal drilling machines.

 

4.wood drills

1)wood drill bit,with two shouldered cutting deges

*Brad point and two shouldered cutting edges.

*Cylindric shank.

Right hand cutting.

Designed to drill:soft wood,non coated chipboards.

 

2)cylinder boring bit,carbide tipped

*fastest drill bit for wood due to 4-flute geometry for faster chip efection.

*Aggressive thread point enabled precise spot drilling with little expenditure of energy.

*faster han conventional machine flat bits.

*Designed to drill:all kinds of wood,especially for very hard and hardest tropical wood.

 

3)sorgers-for drilling all types of wood

*Not always available-minimum manufacture quantity may apply.

 

4)auger bit & flat bits

 

auger bits

*suitable for precise drilling in soft and hard wood,large section beam,chipboard and plywood

*precision machined for smooth,wobble free boring.Large,wide throat design gives excellent chip cleareance form deep holes

*self-feeding screw point,with one cuttign edge and side lip for last,rough boring in wood

*hardened cutting edges require less re-sharpening.Overall length 200/460mm available for each size.

 

flat bits

*point:sharpened center point with flute.Cuttign edge:2 major cutting edges,guarantee a peeled cut.

Shank:hexagon shank up to the span of the jaw of 6mm.Conical side cutting edges prevent the wedging in the wood

*Material:high quality tool steel

*Normal style suitable for cutting wood and chipboard,bit with curved cutter for cuttign smooth hole,bit with tri-point for cutting wood and chipboard with smooth hole.

 

 

5.forstner bits

1)forstner bit,toothed

*Two cutting edges and circumferential balade.

  *With brad point.Equivalent to DIN 7483 G.Long life tool.Designed to drill:Soft wood and veneered wooden board.

 

2)forstneer bit

*Two cutting-edges and circumferential blade

  *With brad point.Equivalent to DIN 7483 G.Designed to drill:soft wood and veneered wooden board.

 

 

3)Cylinder boring bit,carbide tipped

 *With brad point,two cutting edges and two raised lips made of carbide.

 *Carbide tipped cutters last longer even when drilling in more difficult materials.

 *For professional use and exact,splinter free drilling.
