The carbide tipped drill bit 1593:
The task of drilling exotic and extremely hard wood
species places very specific and extreme demands on the tools used. Twist
drills are very suitable for deep drilling due to their geometry, but in the
hardest woods heat can build up rapidly at the cutting face leading to
premature dulling and inaccuracy. This problem is exacerbated when low-quality
tools are used, but even very hard and sharp HSS tools can reach their limits
under certain conditions.
We know from experience that when drilling in hardwood,
the chips tend to break “short“. These hardwood chips have a significantly
smaller volume than soft wood chips. Completely different tasks are imposed on
the geometry of the spiral of a hardwood drill compared to drills which are
designed to work in softwood, examine the flutes of a Lewis Auger for example.
For the specific demands of drilling hardwood we have
created a new carbide tipped woodworking drill bit: the FAMAG 1593 series. The
‘Type N’ spirals are ground with a very steep slope. Twin flutes without a back
guide provide minimal friction in the bore and thus considerably reduce heat
generation in the drill bit and the release of resins from the timber. The steep
helix ensures that hardwood chips are ejected quickly from the drill bit,
preventing debris build up and eliminating a second potential source of
friction.
Carbide is insensitive to heat and is well suited for cutting
exotic hardwoods. Our new CNC machine – built especially for the task – forms
the spurs, centre point and two main cutting edges of the new bits. With this
overall geometry, careful material selection, and precision manufacturing
process, the new 1593 TCT drills are perfect for the working of European and
exotic hardwoods, they also perform superbly on hard coatings, chipboard,
laminate and hard plastics like Corian.
The 1593 TCT wood drill is available in sizes from 3.0 mm - 12.0 mm and can be ordered in sets or individually:Article number: 1593.805:5 pieces in blister with the Ø 3, 4, 5, 6 and 8 mm
Article number: 1593.507:
7 pieces in high-quality wooden box with Ø 3, 4, 5, 6, 8, 10 and 12 mm
Article number: 1593.510:
10 pieces in high-quality wooden box with Ø 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12 mm
The VARIO-Countersink 2202:
High quality carbide tips make VARIO the perfect
partner for 1593 TCT drills.
Everyone knows the problem: When drilling and making countersinks in
wood – in one operation - the appropriate countersink is not at hand. Or a hole
must be drilled with an intermediate size for which there is no standard
countersink. This is where the FAMAG carbide tipped VARIO countersink excels
since you can mount variable twist drills of Ø 3 mm to Ø 8 mm. The tool
consists of two half shells which are fastened by means of two clamping screws
on the drill.
Cheaper versions
typically clamp with only one screw, acting on the spiral groove of the drill. This
often causes poor concentricity with small drill diameters. Our concentric twin
shell design, and the carbide tips, are what makes the FAMAG VARIO countersink
fundamentally different.
