Home batsman Ben Wright was the only batsman to reach a landmark as 15 wickets fell on the first day of Glamorgan's LV= County Championship Division Two clash with Kent at the SWALEC Stadium.
Wright claimed the lone half-century on a day for the bowlers, which saw Kent's Darren Stevens claim figures of 4-34.
Stevens helped reduce Glamorgan, who won the toss, to 158 all out in 60 overs before Kent also struggled to reach 102 for five by the close.
That was after Australian seamer Michael Hogan bowled openers Sam Northeast and Rob Key to claim his 56th and 57th victims of the season.
The next two wickets to fall were also bowled as Brendan Nash and Ben Harmison had their defences breached by 19-year-old debutant Ruadhri Smith and Mike Reed respectively.
Daniel Bell-Drummond, who finished the day on 41 not out, and Stevens steadied Kent before the latter became Hogan's third victim when edging to second slip.
Stevens had earlier struck three times in his opening five overs to demolish the Glamorgan top order.
He initially broke through Gareth Rees' defences before having Will Bragg caught behind by Geraint Jones and continued his productive spell by dismissing Chris Cooke.
Glamorgan reached lunch at 64 for three but three overs after the interval Charlie Shreck bagged the crucial wicket of Murray Goodwin, who had scored 178 against Leicestershire a fortnight ago.
The veteran Zimbabwean was caught at short extra-cover by Northeast.
Glamorgan reached 100 in the 39th over but Jim Allenby soon exited, caught behind off an inside-edge from Mark Davies.
And 102 for five became 127 for six when skipper Mark Wallace miscued a pull to midwicket.
While Wright edged towards an impressive half-century, the wickets kept falling at the other end as Smith edged Calum Haggett behind.
Wright brought up his fifty from 91 deliveries before he too departed lbw to Adam Riley's off-spin, which accounted for Hogan two balls later.
The innings ended when Stevens trapped Reed lbw.
